In each and every place of pilgrimage, the Lord is present in His various transcendental forms. These forms are called arcā-mūrtis, or forms of the Lord which can be easily appreciated by the common man. The Lord is transcendental to our mundane senses. He cannot be seen with our present eyes, nor can He be heard with our present ears. To the degree that we have entered into the service of the Lord or to the proportion to which our lives are freed from sins, we can perceive the Lord. But even though we are not free from sins, the Lord is kind enough to allow us the facility of seeing Him in His arcā-mūrtis in the temple.
(Srimad Bhagavatam----3:1:17----purport).

The Lord is all-powerful, and therefore He is able to accept our service by presentation of His arcā form. No one, therefore, should foolishly think the arcā in the temple to be an idol. Such an arcā-mūrti is not an idol but the Lord Himself, and to the proportion to which one is free from sins, he is able to know the significance of the arcā-mūrti. The guidance of a pure devotee is therefore always required.
(Srimad Bhagavatam----3:1:17----purport).

In the land of Bhāratavarṣa there are many hundreds and thousands of places of pilgrimage distributed all over the country, and by traditional practice the common man visits such holy places during all seasons of the year. Some of the arcā representations of the Lord situated in different places of pilgrimage are mentioned herewith. The Lord is present at Mathurā (the birthplace of Lord Kṛṣṇa) as Ādi-keśava; the Lord is present at Purī (Orissa) as Lord Jagannātha (also known as Puruṣottama); He is present at Allahabad (Prayāga) as Bindu-mādhava; at Mandara Hill He is present as Madhusūdana. In the Ānandāraṇya, He is known as Vāsudeva, Padmanābha and Janārdana; at Viṣṇukāñcī, He is known as Viṣṇu; and at Māyāpura, He is known as Hari. There are millions and billions of such arcā forms of the Lord distributed all over the universe. All these arcā-mūrtis are summarized in the Caitanya-caritāmṛta in the following words:
sarvatra prakāśa tāṅra—bhakte sukha dite
jagatera adharma nāśi' dharma sthāpite
"The Lord has so distributed Himself all over the universe just to give pleasure to the devotees, to give the common man facility to eradicate his sins, and to establish religious principles in the world."
(Srimad Bhagavatam----3:1:17----purport).

There is no difference between the potencies of the arcā and those of the personal forms of the Lord. The example of the postbox and post office may be applied here. The little postboxes distributed all over the city have the same potency as the postal system in general. The duty of the post office is to carry letters from one place to another. If one puts letters in postboxes authorized by the general post office, the function of carrying letters is performed without a doubt. Similarly, the arcā-mūrti can also deliver the same unlimited potency of the Lord as when He is personally present. Vidura, therefore, could see nothing but Kṛṣṇa in the different arcā forms, and ultimately he was able to realize Kṛṣṇa alone and nothing else.
(Srimad Bhagavatam----3:1:18----purport).

By spiritual energy, the Lord can appear in a body made of wood or stone. He can change His body into anything because everything is His energy (parāsya śaktir vividhaiva śrūyate (Cc. Madhya 13.65, purport)). As clearly said in Bhagavad-gītā (7.4), bhinnā prakṛtir aṣṭadhā: the material elements are separated energies of the Supreme Lord. If He transforms Himself into the arcā-mūrti, the worshipable Deity, which we see as stone or wood, He is still Kṛṣṇa. Therefore the śāstra warns, arcye viṣṇau śilā-dhīr guruṣu nara-matiḥ. One who thinks that the worshipable Deity in the temple is made of wood or stone, one who sees a Vaiṣṇava guru as an ordinary human being, or one who materially conceives of a Vaiṣṇava as belonging to a particular caste is nārakī, a resident of hell.
(Srimad Bhagavatam----3:3:46----purport).

As we have several times explained, no one can separate the sunshine energy from the energetic sun. Therefore material energy may appear separate from the Lord, but transcendentally it is nondifferent from the Lord. The Lord can appear anywhere and everywhere because His diverse energies are distributed everywhere like sunshine. We should therefore understand whatever we see to be the energy of the Supreme Lord and should not differentiate between the Lord and His arcā form made from clay, metal, wood or paint. Even if one has not developed this consciousness, one should accept it theoretically from the instructions of the spiritual master and should worship the arcā-mūrti, or form of the Lord in the temple, as nondifferent from the Lord.
(Sri Caitanya Caritamrta----1:5:226----purport).

One who thinks that there is a difference between Lord Viṣṇu's body and His soul dwells in the darkest region of ignorance. There is no difference between Lord Viṣṇu's body and Viṣṇu's soul, for they are advaya-jñāna, one knowledge. In this world there is a difference between the material body and the spiritual soul, but in the spiritual world everything is spiritual and there are no such differences. The greatest offense of the Māyāvādī philosophers is to consider Lord Viṣṇu and the living entities to be one and the same. In this connection the Padma Purāṇa states, arcye viṣṇau śilā-dhir guruṣu nara-matir vaiṣṇave jāti-buddhiḥ . . yasya vā nārakī saḥ: "One who considers the arcā-mūrti, the worshipable Deity of Lord Viṣṇu, to be stone, the spiritual master to be an ordinary human being, and a Vaiṣṇava to belong to a particular caste or creed is possessed of hellish intelligence." One who follows such conclusions is doomed.
(Sri Caitanya Caritamrta----1:7:115----purport).

The conversation between Lord Śrī Kṛṣṇa and the brāhmaṇa is proof that the Lord in His arcā-mūrti, or form made of material elements, is not material, for those elements, although separated from the Lord, are also a part of the Lord's energy, as stated in the Bhagavad-gītā. Because the elements are the Lord's own energy and because there is no difference between the energy and the energetic, the Lord can appear through any element. Just as the sun can act through the sunshine and thus distribute its heat and light, so Kṛṣṇa, by His inconceivable power, can appear in His original spiritual form in any material element, including stone, wood, paint, gold, silver and jewels, because the material elements are all His energy. The śāstras warn, arcye viṣṇau śilā-dhīḥ . . . nārakī saḥ: one should never think of the arcā-mūrti, the Deity within the temple, as stone, wood or any other material element. Because of his advanced devotional position, the younger brāhmaṇa knew that although the Deity of Gopāla appeared to be stone, He was not stone. He was the son of Nanda Mahārāja, Vrajendra-nandana Himself. As such, the Deity could act exactly as the Lord does in His original form as Kṛṣṇa.
(Sri Caitanya Caritamrta----2:5:97----purport).

All of these forms are mūrti forms, and They are worshiped in the temples. Their names are Keśava at Mathurā, Puruṣottama or Jagannātha at Nīlācala, Śrī Bindu Mādhava at Prayāga, Madhusūdana at Mandāra, and Vāsudeva, Padmanābha and Janārdana at Ānandāraṇya, which is situated in Kerala, South India. At Viṣṇu-kāñcī is Lord Varadarāja, and Hari is situated at Māyāpur, Lord Caitanya's birth site. Thus in different places throughout the universe there are various Deities in temples bestowing Their causeless mercy upon the devotees. All these Deity forms are nondifferent from the mūrtis in the spiritual world of the Vaikuṇṭhas. Although the arcā-mūrti, the worshipable Deity form of the Lord, appears to be made of material elements, it is as good as the spiritual forms found in the spiritual Vaikuṇṭhalokas. The Deity in the temple, however, is visible to the material eyes of the devotee. It is not possible for one in material, conditioned life to see the spiritual form of the Lord. To bestow causeless mercy upon us, the Lord appears as the arcā-mūrti so that we can see Him. It is forbidden to consider the arcā-mūrti to be made of stone or wood.
(Sri Caitanya Caritamrta----2:20:217----purport).

In the material world, the Lord is situated in different arcā-mūrtis (Deities) in the temples just to decrease the material activities of the conditioned soul and increase his spiritual activities. Particularly in India there are many temples throughout the country. Devotees may take advantage of them and go see the Lord at Jagannātha Purī, Vṛndāvana, Prayāga, Mathurā, Hardwar and Viṣṇu-kāñcī. When the devotees travel to these places and see the Lord, they become very happy in devotional service.
(Sri Caitanya Caritamrta----2:20:219----purport).

First-class men, let them become scholars, philosophers, preachers, instructors, brahminical business. Paṭhana pāṭhana yajana yājana dāna pratigrahaḥ. These are the six businesses for the brāhmaṇa class. They should be highly educated, paṭhana, highly learned, and pāṭhana, and they should educate others also. But if he is not educated, how he will educate others? Paṭhana pāṭhana yajana yājana. He should be worshipper of the Supreme Lord, yajana, and yājana, he should instruct others also.
śrī-vigrahārādhana-nitya-nānā-
śṛṅgāra-tan-mandira-mārjanādau
yuktasya bhaktāṁś ca niyuñjato 'pi
vande guroḥ śrī-caraṇāravindam **
Śrī-vigraha. This is yajana yājana. Śrī-vigraha. This is Śrī-vigraha, Kṛṣṇa's arcā-mūrti. Kṛṣṇa has taken, advented, as avatāra, arcā-avatāra. Arcā-avatāra means made of stone, wood, metal, jewel, or coloring, painting. There are eight kinds of arcā-avatāra. So Kṛṣṇa has consented to descend before us to accept our service in a manner which we can do.
(Lecture on Bhagavad-Gita----4:15).

Kṛṣṇa says mayy āsakta-manāḥ, "Unto Me become attached." Āsakta, attached. So how this attachment will increase? Mayy āsakta-manāḥ yogaṁ yuñjan, this is a yoga, to become attached to Kṛṣṇa. This is the beginning. If you come to the temple daily and you see the transcendental form, sac-cid-ānanda-vigraha (Bs. 5.1) of Bhagavān... This Bhagavān which you see, it is nondifferent from the original Bhagavān. Don't differentiate, that "This is a stone statue of Bhagavān." No. He is Bhagavān. He is Bhagavān, arcā-mūrti, arcā-vigraha. Because we cannot see Bhagavān with our present eyes—ataḥ śrī-kṛṣṇa-nāmādi na bhaved grāhyam indriyaiḥ (CC.2:17:136). With the present blunt senses we cannot see Bhagavān. Therefore Bhagavān, out of His causeless mercy, has appeared in a form which you can see. Not that He's different. He's not different. Because Bhagavān is everything. That will be explained. So He can appear in any form. So He has appeared in a form which you can see. That is Bhagavān's mercy. Not that He is statue. Arcye viṣṇau śilā-dhīr guruṣu nara-matir vaiṣṇave jāti-buddhir nārakī-buddhiḥ. If we consider that "Here is a stone statue," arcye viṣṇau śilā-dhīḥ. No śilā. No, it is not. Bhagavān is everything. By the advancement of knowledge, we'll understand Bhagavān, "Here is Bhagavān."
(Lecture on Bhagavad-Gita----7:1).

So humbly, so fearfully, they are engaged in Kṛṣṇa's service. What Kṛṣṇa's service we can give? What we are? We are nothing. Insignificant. So why Kṛṣṇa accepts our service? Why He comes in His arcā-mūrti to accept our service? Just to induce you how to serve Him, bhakti. That is wanted. Therefore He says, "So you give Me even patraṁ puṣpaṁ phalaṁ toyam (B.G.9:26). It doesn't matter. But give Me with bhakti." Yo me bhaktyā prayacchati. This is real business. (?) If you have no bhakti, if you officially make, Kṛṣṇa does not touch it. Kṛṣṇa is not so poor. Lakṣmī-sahasra-śata-sambhrama-sevyamānaṁ govindam ādi-puruṣaṁ tam... (Bs. 5.29). So whatever you do, you should always be humble: "Kṛṣṇa, I am quite unfit. So whatever I could collect with my capacity, kindly accept." This is our only plea. Otherwise, don't be proud that "I am doing so much for Kṛṣṇa. Kṛṣṇa will be obliged to accept it." It is not like that. Tṛṇād api sunīcena taror api sahiṣṇunā. This is wanted.
(Lecture on Bhagavad-Gita----7:9).

So it is Kṛṣṇa's kindness that He has appeared before you in a small form, so according to your capacity, you can make very nice dress, and Kṛṣṇa, you can dress Him. And by dressing Him, Kṛṣṇa will understand that "Here is my devotee. He is giving Me some service." This is the position. Therefore temple worship, the Deity worship is necessity for the kaniṣṭha-adhikārī. Simply if you think that "Kṛṣṇa is everywhere. I shall think of Kṛṣṇa, meditate on Him," that is not possible. Meditation, that is also regu..., requires good qualification. Dhyānāvasthita-tad-gatena manasā paśyanti yaṁ yoginaḥ (S.B.12:13:1). But Kṛṣṇa, by His kindness, arca-mūrti, a child can see also Kṛṣṇa. Any innocent, any illiterate man can see, any man can see—a brāhmaṇa can see, śūdra can see. Therefore the Deity worship so important.
(Lecture on Bhagavad-Gita----9:4).

So we do not know actually in truth what is God; therefore with our material conception we think that God is nirākāra. God is not nirākāra. He has ākāra, but we have no power to see Him. And because we have no power to see Him, therefore God takes the form like this. He's God, He's not different from God, but He's visible to our blunt eyes. Therefore we say sometimes, "It is idol." He's not idol. We are not worshiping idol, stone. Just like some rascal says that "If by worshiping stone, God is available, then I can worship the mountain." Pathar pūjā ke hari mile meita puje pahar(?). So this rascal does not know that this is not worship of pathar. It is worship of the Supreme Personality of Godhead personally, but to show us mercy, because we cannot see the Supreme Personality of Godhead with these blunt eyes, He has assumed the form of a stone. This is called arcā-mūrti. It is His mercy.
(Lecture on Bhagavad-Gita----13:15).

Just like we have no knowledge of Kṛṣṇa, conditioned soul. Therefore for our understanding, He is so merciful, He descends as arcā-mūrti. This Deity which we are worshiping, that is called arcāvatāra, incarnation of arcā. He's accepting our worship, our prayer, our everything. He has descended just suitable for our handling. That is His mercy. Therefore we should not consider that this arcā Kṛṣṇa is made of stone, as atheists will say, that "These foolish persons are worshiping... Heathens, they are worshiping." No, we are not worshiping stone. We are worshiping Kṛṣṇa. But that they do not know. Kṛṣṇa has appeared before us. Because at the present moment, we cannot see except stone and wood, therefore, suitable for our vision, He has appear in such a way. Otherwise how we can appreciate? Here... They are searching after what is God, but here is God. Here is God. Therefore in the śāstra it is forbidden, arcā, arcye viṣṇau śilā-dhīr guruṣu nara-matir vaiṣṇave jāti-buddhiḥ. It is forbidden that when you worship Deity, you should not think that it is made of wood or stone or something else material.
(Lecture on Srimad Bhagavatam----1:15:27).

One portion of Kṛṣṇa, Paramātmā, just to create this material world, He has entered in the mahat-tattva as Mahā-Viṣṇu, and He entered within the universe as Garbhodakaśāyī-Viṣṇu, He has entered everyone's heart as Supersoul, Kṣīrodakaśāyī-Viṣṇu, and He has entered into the atom-although He is so great. So it is Kṛṣṇa's mercy that He can become smaller than the smallest and the greater than the greatest. So we cannot capture the greater than the greatest. That is not possible. Therefore it is His kindness that He has become just to be handled by you. This is called arcā-mūrti. Arcā-vigraha. The Deity worship means arcā-vigraha.
(Lecture on Srimad Bhagavatam----2:1:2).

So God is all-good, always. Even if He kills one or even if He protects one, the ultimate result is the same. Therefore Parīkṣit Mahārāja is advised that tasmād bhārata sarvātmā (S.B.2:1:5). Sarvātmā means He is all-pervasive. He is living in everyone's heart. He knows everyone in particular details, and, at the same time, He is personally present also, personally present. How He is personally present? Just like in this temple, He's personally present. This arcā-mūrti, it is not idol worship. You practically try to understand. If it was idol worship, idol worship, then these boys and girls, they are American boys and girls, intelligent, educated, they should not have spared so much time for worshiping one idol. No. It is God's mercy that He incarnates Himself as we can handle Him. If we want to worship His gigantic universal form, we cannot approach Him. It is not possible. But He's so kind. He comes just suitable for our, for our being handled by us. That is God's mercy.
(Lecture on Srimad Bhagavatam----2:1:5).

Simply by appreciating, if they say, "Now the Deity worship is very nice," then they go a step forward, step forward immediately, simply by appreciation. Then other things will come gradually. Therefore the temple worship should be exactly to the routine, to the instruction of the śāstra and guru and ācārya, so that the worshiper in the temple as well as the visitor, both of them will benefit. They will be gradually seeing. Kṛṣṇa is so kind that He has consented to appear in a way so that we can see. At the present moment we cannot see Kṛṣṇa as He is spiritually embodied, sad-cid-ānanda-vigrahaḥ, because we have no eyes to see sac-cid-ānanda-vigrahaḥ (Bs. 5.1). So here is also sac-cid-ānanda-vigrahaḥ, arcā-mūrti. It is not idol worship. The atheist class may say so, but it is not so. Those who have got eyes, they can see. Just like Caitanya Mahāprabhu. Caitanya Mahāprabhu, when He entered the temple of Jagannātha, immediately He fainted, "Oh, here is My Lord. Here is My Lord." So one has to become santaḥ. Then one can see. But it is culture, by culture.
(Lecture on Srimad Bhagavatam----3:25:35).

Somebody was talking that "Your Deity is just like trying to talk with me." Prasanna-vaktra. Yes. He is here to talk with you, but He is waiting whether you're interested to talk with Him. That's all. Kṛṣṇa says that teṣāṁ satata-yuktānāṁ bhajatāṁ prīti-pūrvakam, buddhi-yogaṁ dadāmi tam (B.G.10:10). He talks, but with whom? Teṣāṁ satata-yuktānām. One who is twenty-four hours engaged with love and faith in the service of the Lord. To whom? Just like if you want to talk with some big man, then you must have qualification. Is it possible that if you want to talk with the big man here, immediately you like? No. You cannot talk. You must be fit to talk with him. Similarly, Kṛṣṇa is ready to talk with you. He has come. He has descended in arcā-mūrti to talk with you, to be visible by you. Now you make yourself ready and fit to talk with Kṛṣṇa. Then He will exchange conversation. Santaḥ sadaiva hṛdayeṣu vilokayanti. This is possible. This is a qualification.
(Lecture on Srimad Bhagavatam----3:25:35).

So due to this nonsensical meaning, people are puzzled, that "Whom to surrender? Because Kṛṣṇa I do not see." No. Kṛṣṇa is always existing. So you can... Kṛṣṇa is existing, and to be perceivable by you, Kṛṣṇa has appeared before you. Here is the arcā-mūrti. The arcā-mūrti we are serving. It is not that... Don't think. Arcye viṣṇau śilā-dhīḥ. If you are rascal, they will think that "These people are serving a stone statue." The rascals will think like that, but that is not the fact. Here, practical serving of Kṛṣṇa. The same ācārya has taught that here is Kṛṣṇa. Śrī-vigrahārādhana-nitya-nānā-śṛṅgāra-tan-mandira-mārjanādau **. Śrī-vigraha. This arcā-mūrti, śrī-vigraha, ārādhanam, you should worship. This is the ācārya-panthā. This is the paramparā.
(Lecture on Srimad Bhagavatam----3:26:32).

So we request everyone to come to the temple because he will have the impression what is Kṛṣṇa, how He looks. Here is Kṛṣṇa. It is not imagination. Don't think it is imagination, we have imagined some form. Just like the Māyāvādīs say, "It is imagination." No. It is fact. Because this Kṛṣṇa, this form of Kṛṣṇa, the our forefathers or ācāryas they have seen when Kṛṣṇa was present on this planet. And there are many, many old temples. The same feature of Kṛṣṇa, two hands, playing on the flute, and anywhere you will see Kṛṣṇa He has got this flute. Because that is His most beloved, favorite instrument. That is stated in the śāstra, not imagination. Veṇuṁ kvaṇantam aravinda-dalāyatākṣaṁ barhāvataṁsam asita... (Bs. 5.30). In the Vedic language it is said that Kṛṣṇa, He has got a flute in His hand. He likes to play on flute. Veṇuṁ kvaṇantam aravinda-dalāyatākṣaṁ barhāvataṁsam asitāmbuda-sundarāṅgam (Bs. 5.30). Barhāvataṁsa means the peacock. He likes peacock feather. These symptoms are described in the Vedic literature, and when Kṛṣṇa was present on this earth, the same feature was there. So this picture, this photo, or this statue of Kṛṣṇa, this arcā-mūrti, is not different from the original Kṛṣṇa.
(Lecture on Srimad Bhagavatam----3:26:43).

Our knowledge is sense perception. Sense perception, akṣaja jñānam. That will not act there. Acintya. Therefore we have to accept in that way. Idaṁ śarīram, but He has His body. He has His body, and because we cannot conceive, He, out of His causeless mercy, He presents Himself in a form which we can see. That is arcā-vigraha, arcā-mūrti. A vigraha. Arcā means the form which we can worship. If God is impersonal Avyaktāsakta-cetasām. Kleśo adhikataras teṣām. If we accept God as impersonal He is not impersonal. He says idaṁ śarīram. He is personal. But our present senses cannot perceive. That is the difficulty. Therefore out of His causeless mercy He has appeared in a form which you can see, you can touch, you can dress, you can offer garland, you can offer food—to accept your service. That is God's mercy. Don't think that "Because God mercifully has come before Me in a form which we can perceive, which we can see, with which we can serve," not that "He is not God." That is rascaldom. God is there. Otherwise Caitanya Mahāprabhu, as soon as He entered the Jagannātha's temple, immediately He fainted. Does it mean He made a fun? No. He saw the Supreme Personality of Godhead present there.
(Lecture on Srimad Bhagavatam----5:5:19).
