“The living entities are energies, not the energetic. The energetic is Kṛṣṇa. This is very vividly described in the Bhagavad-gītā, the Viṣṇu Purāṇa and other Vedic literatures.
As already explained, there are three prasthānas on the path of advancement in spiritual knowledge—namely, nyāya-prasthāna (Vedānta philosophy), śruti-prasthāna (the Upaniṣads and Vedic mantras) and smṛti-prasthāna (the Bhagavad-gītā, Mahābhārata, Purāṇas, etc.). Unfortunately, Māyāvādī philosophers do not accept the smṛti-prasthāna. Smṛti refers to the conclusions drawn from the Vedic evidence. Sometimes Māyāvādī philosophers do not accept the authority of the Bhagavad-gītā and the Purāṇas, and this is called ardha-kukkuṭī-nyāya, "the logic of half a hen" (See Ādi-līlā 5.176). If one believes in the Vedic literatures, one must accept all the Vedic literatures recognized by the great ācāryas, but the Māyāvādī philosophers accept only the nyāya-prasthāna and śruti-prasthāna, rejecting the smṛti-prasthāna. Here, however, Śrī Caitanya Mahāprabhu cites evidence from the Gītā, Viṣṇu Purāṇa, etc., which are smṛti-prasthāna. No one can avoid the Personality of Godhead in the statements of the Bhagavad-gītā and other Vedic literatures such as the Mahābhārata and the Purāṇas. Lord Caitanya therefore quotes a passage from the Bhagavad-gītā (7.5).

(Sri Caitanya Caritamrta-----1:7:117-----translation and purport).

“"The potency of Lord Viṣṇu is summarized in three categories—namely, the spiritual potency, the living entities and ignorance. The spiritual potency is full of knowledge; the living entities, although belonging to the spiritual potency, are subject to bewilderment; and the third energy, which is full of ignorance, is always visible in fruitive activities."
This is a quotation from the Viṣṇu Purāṇa (6.7.61).

In the previous verse, quoted from the Bhagavad-gītā, it has been established that the living entities are to be categorized among the Lord's potencies. The Lord is potent, and there are varieties of potencies (parāsya śaktir vividhaiva śrūyate (Cc. Madhya 13.65, purport)). Now, in this quotation from the Viṣṇu Purāṇa, this is further confirmed. There are varieties of potencies, and they have been divided into three categories—namely, spiritual, marginal and external.

The spiritual potency is manifested in the spiritual world. Kṛṣṇa's form, qualities, activities and entourage are all spiritual. This is confirmed in the Bhagavad-gītā (4.6):

ajo ’pi sann avyayātmā bhūtānām īśvaro ’pi san
prakṛtiṁ svām adhiṣṭhāya sambhavāmy ātma-māyayā
(B.G.4:6)
"Although I am unborn and My transcendental body never deteriorates, and although I am the Lord of all living entities, by My spiritual potency I still appear in every millennium in My original transcendental form." Ātma-māyā refers to the spiritual potency. When Kṛṣṇa comes to this or any other universe, He does so with His spiritual potency. We take birth by the force of the material potency, but as stated here with reference to the Viṣṇu Purāṇa, the kṣetra-jña, or living entity, belongs to the spiritual potency; thus when we free ourselves from the clutches of the material potency we can also enter the spiritual world.

(Sri Caitanya Caritamrta-----1:7:119-----translation and purport).

In this verse from the Viṣṇu Purāṇa the total energy of the Supreme Personality of Godhead is classified in three divisions—namely, the spiritual or internal potency of the Lord, the marginal potency, or kṣetra-jña (the living entity), and the material potency, which is separated from the Supreme Personality of Godhead and appears to act independently. When Śrīla Vyāsadeva, by meditation and self-realization, saw the Supreme Personality of Godhead, he also saw the separated energy of the Lord standing behind Him (apaśyat puruṣaṁ pūrṇaṁ māyāṁ ca tad-apāśrayam). Vyāsadeva also realized that it is this separated energy of the Lord, the material energy, that covers the knowledge of the living entities (yayā sammohito jīva ātmānaṁ tri-guṇātmakam (S.B.1:7:5). The separated, material energy bewilders the living entities (jīvas), and thus they work very hard under its influence, not knowing that they are not fulfilling their mission in life. Unfortunately, most of them think that they are the body and should therefore enjoy the material senses irresponsibly since when death comes everything will be finished.

(Sri Caitanya Caritamrta-----1:7:119----- purport).

In the Vedānta-sūtra, Vyāsadeva has described that the Supreme Personality of Godhead is potent and that everything, material or spiritual, is but an emanation of His energy. The Lord, the Supreme Brahman, is the origin or source of everything (janmādy asya yataḥ (S.B.1:1:1), and all other manifestations are emanations of different energies of the Lord. This is also confirmed in the Viṣṇu Purāṇa:
eka-deśa-sthitasyāgner jyotsnā vistāriṇī yathā
parasya brahmaṇaḥ śaktis tathedam akhilaṁ jagat
"Whatever we see in this world is simply an expansion of different energies of the Supreme Personality of Godhead, who is exactly like a fire that spreads illumination for a long distance although it is situated in one place." This is a very vivid example. Similarly, it is stated that just as everything in the material world exists in the sunshine, which is the energy of the sun, so everything exists on the basis of the spiritual and material energies of the Supreme Personality of Godhead. Thus although Kṛṣṇa is situated in His own abode (goloka eva nivasaty akhilātma-bhūtaḥ (Bs. 5.37)), where He enjoys His transcendental pastimes with the cowherd boys and gopīs, He is nevertheless present everywhere, even within the atoms of this universe (aṇḍāntara-stha-paramāṇu-cayāntara-stham (Bs. 5.35)). This is the verdict of the Vedic literature.

(Sri Caitanya Caritamrta-----1:7:120----- purport).

The Bhāgavatam says that it is the duty of an advanced human being to act in such a way as to facilitate human society's attainment of the ultimate goal of life. There is a similar verse in the Viṣṇu Purāṇa, Part Three, Chapter Twelve, verse 45, which is next quoted in the Caitanya-caritāmṛta.

(Sri Caitanya Caritamrta-----1:9:42----- purport).

The actual Vedic system of religion is called varṇāśrama-dharma, as confirmed in the Viṣṇu Purāṇa:
varṇāśramācāra-vatā puruṣeṇa paraḥ pumān
viṣṇur ārādhyate panthā nānyat tat-toṣa-kāraṇam
(CC.2:8:58 (Viṣṇu Purāṇa 3.8.9)

The Vedic literature recommends that a human being follow the principles of varṇāśrama-dharma. Accepting the process of varṇāśrama-dharma will make a person's life successful because this will connect him with the Supreme Personality of Godhead, who is the goal of human life. Therefore the Kṛṣṇa consciousness movement is meant for all of humanity. Although human society has different sections or subdivisions, all human beings belong to one species, and therefore we accept that they all have the ability to understand their constitutional position in connection with the Supreme Personality of Godhead, Viṣṇu.

(Sri Caitanya Caritamrta-----1:12:73----- purport).

"The Vedic statements are self-evident. Whatever is stated there must be accepted. If we interpret according to our own imagination, the authority of the Vedas is immediately lost."
Out of four main types of evidence—direct perception, hypothesis, historical reference and the Vedas—Vedic evidence is accepted as the foremost. If we want to interpret the Vedic version, we must imagine an interpretation according to what we want to do. First of all, we set forth such an interpretation as a suggestion or hypothesis. As such, it is not actually true, and the self-evident proof is lost.

Śrīla Madhvācārya, commenting on the aphorism dṛśyate tu (Vedānta-sūtra 2.1.6), quotes the Bhaviṣya Purāṇa as follows:

ṛg-yajuḥ-sāmātharvāś ca bhārataṁ pañcarātrakam
mūla-rāmāyaṇaṁ caiva veda ity eva śabditāḥ
purāṇāni ca yānīha vaiṣṇavāni vido viduḥ
svataḥ-prāmāṇyam eteṣāṁ nātra kiñcid vicāryate
The Ṛg Veda, Yajur Veda, Sāma Veda, Atharva Veda, Mahābhārata, Pañcarātra and original Rāmāyaṇa are all considered Vedic literature. The Purāṇas (such as the Brahma-vaivarta Purāṇa, Nāradīya Purāṇa, Viṣṇu Purāṇa and Bhāgavata Purāṇa) are especially meant for Vaiṣṇavas and are also Vedic literature. As such, whatever is stated within the Purāṇas, Mahābhārata and Rāmāyaṇa is self-evident. There is no need for interpretation. The Bhagavad-gītā is also within the Mahābhārata; therefore all the statements of the Bhagavad-gītā are self-evident. There is no need for interpretation, and if we do interpret, the entire authority of the Vedic literature is lost.

(Sri Caitanya Caritamrta-----2:6:137-----translation and purport).

The living entities are described as ananta, or unlimited; nonetheless, they are said to belong to 8,400,000 species. As stated in the Viṣṇu Purāṇa:
jala-jā nava-lakṣāṇi sthāvarā lakṣa-viṁśati
kṛmayo rudra-saṅkhyakāḥ pakṣiṇāṁ daśa-lakṣaṇam
triṁśal-lakṣāṇi paśavaḥ catur-lakṣāṇi mānuṣāḥ
"There are 900,000 species living in the water. There are also 2,000,000 nonmoving living entities (sthāvara), such as trees and plants. There are also 1,100,000 species of insects and reptiles, and there are 1,000,000 species of birds. As far as quadrupeds are concerned, there are 3,000,000 varieties, and there are 400,000 human species." Some of these species may exist on one planet and not on another, but in any case within all the planets of the universe—and even in the sun—there are living entities. This is the verdict of the Vedic literatures.

(Sri Caitanya Caritamrta-----2:19:138------ purport).

“"Just as the illumination of a fire, which is situated in one place, is spread all over, the energies of the Supreme Personality of Godhead, Parabrahman, are spread all over this universe."
This is a quotation from the Viṣṇu Purāṇa (1.22.53).

(Sri Caitanya Caritamrta-----2:20:110------ translation and purport).

“"Originally, Kṛṣṇa"s energy is spiritual, and the energy known as the living entity is also spiritual. However, there is another energy, called illusion, which consists of fruitive activity. That is the Lord's third potency.’
This is a quotation from the Viṣṇu Purāṇa (6.7.61). For a further explanation of this verse, refer to Ādi-līlā, Chapter Seven, verse 119.

(Sri Caitanya Caritamrta-----2:20:112------ translation and purport).

“"All the creative energies, which are inconceivable to a common man, exist in the Supreme Absolute Truth. These inconceivable energies act in the process of creation, maintenance and annihilation. O chief of the ascetics, just as there are two energies possessed by fire—namely heat and light—these inconceivable creative energies are the natural characteristics of the Absolute Truth."
This is also a quotation from the Viṣṇu Purāṇa (1.3.2).

(Sri Caitanya Caritamrta-----2:20:113------ translation and purport).

“‘O King, the kṣetra-jña-śakti is the living entity. Although he has the facility to live in either the material or the spiritual world, he suffers the threefold miseries of material existence because he is influenced by the avidyā (nescience) potency, which covers his constitutional position.
This and the following verse are also quoted from the Viṣṇu Purāṇa (6.7.62–63). For an explanation, see Madhya-līlā, Chapter 6, verses 155–156.

(Sri Caitanya Caritamrta-----2:20:114------ translation and purport).

“"In Dvāpara-yuga the Personality of Godhead appears in a blackish hue. He is dressed in yellow, He holds His own weapons, and He is decorated with the Kaustubha jewel and the mark of Śrīvatsa. That is how His symptoms are described."
This is a quotation from Śrīmad-Bhāgavatam (11.5.27). The śyāma color is not exactly blackish. Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura compares it to the color of the atasī flower. It is not that Lord Kṛṣṇa Himself appears in a blackish color in all the Dvāpara-yugas. In other Dvāpara-yugas, previous to Lord Kṛṣṇa's appearance, the Supreme Lord appeared in a greenish body by His own personal expansion. This is mentioned in the Viṣṇu Purāṇa, Hari-vaṁśa and Mahābhārata.

(Sri Caitanya Caritamrta-----2:20:337------ translation and purport).

“"Whatever result was obtained in Satya-yuga by meditating on Viṣṇu, in Tretā-yuga by performing sacrifices and in Dvāpara-yuga by serving the Lord"s lotus feet can also be obtained in Kali-yuga simply by chanting the Hare Kṛṣṇa mahā-mantra.’

This verse is quoted from Śrīmad-Bhāgavatam (12.3.52). At the present moment in Kali-yuga there are many false meditators who concoct some imaginary form and try to meditate upon it. It has become fashionable to meditate, but people know nothing about the object of meditation. That is explained here. Yad dhyāyato viṣṇum. One has to meditate upon Lord Viṣṇu or Lord Kṛṣṇa. Without referring to the śāstras, so-called meditators aim at impersonal objects. Lord Kṛṣṇa has condemned them in the Bhagavad-gītā (12.5):

kleśo ’dhikataras teṣām avyaktāsakta-cetasām
avyaktā hi gatir duḥkhaṁ dehavadbhir avāpyate
"For those whose minds are attached to the unmanifested, impersonal feature of the Supreme, advancement is very troublesome. To make progress in that discipline is always difficult for those who are embodied." Not knowing how to meditate, foolish people simply suffer, and there is no benefit derived from their spiritual activities.

The same idea expressed in this verse from Śrīmad-Bhāgavatam can be found in the following verse from the Viṣṇu Purāṇa (6.2.17), Padma Purāṇa (Uttara-khaṇḍa 72.25) and Bṛhan-nāradīya Purāṇa (38.97).

(Sri Caitanya Caritamrta-----2:20:345------ translation and purport).

As far as the keśa-avatāra (incarnation of a hair) is concerned, it is mentioned in Śrīmad-Bhāgavatam (2.7.26). The Viṣṇu Purāṇa also states, ujjahārātmanaḥ keśau sita-kṛṣṇau mahā-bala.
Similarly, it is stated in the Mahābhārata (Ādi-parva 189.31–32):

sa cāpi keśau harir uccakarta
ekaṁ śuklam aparaṁ cāpi kṛṣṇam
tau cāpi keśāv āviśatāṁ yadūnāṁ
kule striyau rohiṇīṁ devakīṁ ca
tayor eko balabhadro babhūva
yo ‘sau śvetas tasya devasya keśaḥ
kṛṣṇo dvitīyaḥ keśavaḥ sambabhūva
keśaḥ yo "sau varṇataḥ kṛṣṇa uktaḥ
Thus in Śrīmad-Bhāgavatam, the Viṣṇu Purāṇa and the Mahābhārata there are references to Kṛṣṇa and Balarāma being incarnations of a black hair and a white hair respectively. It is stated that Lord Viṣṇu snatched two hairs—one white and one black—from His head. These two hairs entered the wombs of Rohiṇī and Devakī, members of the Yadu dynasty. Balarāma was born from Rohiṇī, and Kṛṣṇa was born of Devakī. Thus Balarāma appeared from the first hair, and Kṛṣṇa appeared from the second hair. It was also foretold that all the asuras, who are enemies of the demigods, would be cut down by Lord Viṣṇu by His white and black plenary expansions and that the Supreme Personality of Godhead would appear and perform wonderful activities. In this connection, one should see the Laghu-bhāgavatāmṛta, the chapter called Kṛṣṇāmṛta, verses 156–164. Śrīla Rūpa Gosvāmī has refuted this argument about the hair incarnation, and his refutation is supported by Śrī Baladeva Vidyābhūṣaṇa"s commentaries. This matter is further discussed in the Kṛṣṇa-sandarbha (29) and in the commentary known as Sarva-saṁvādinī, by Śrīla Jīva Gosvāmī.

(Sri Caitanya Caritamrta-----2:23:117------ purport).

“"I offer my respectful obeisances to the Absolute Truth, the summum bonum. He is the all-pervasive, all-increasing subject matter for the great yogīs. He is changeless, and He is the soul of all."
This is a quotation from the Viṣṇu Purāṇa (1.12.57).

(Sri Caitanya Caritamrta-----2:24:72------ purport).

“"O best among the Bharatas (Arjuna), four kinds of pious men render devotional service unto Me—the distressed, the desirer of wealth, the inquisitive and he who is searching for knowledge of the Absolute."
This is a quotation from the Bhagavad-gītā (7.16). The word sukṛtinaḥ is very important in this verse. Su means "auspicious," and kṛtī means "meritorious" or "regulated." Unless one follows the regulative principles of religious life, human life is no different from animal life. Religious life means following the principles of varṇa and āśrama. In the Viṣṇu Purāṇa it is said:

varṇāśramācāravatā puruṣeṇa paraḥ pumān
viṣṇur ārādhyate panthā nānyat tat-toṣa-kāraṇam
(CC.2:8:58)
According to religious life, society is divided into four social divisions—brāhmaṇa, kṣatriya, vaiśya and śūdra—and four spiritual divisions—brahmacarya, gṛhastha, vānaprastha and sannyāsa. One needs to be trained to become a brāhmaṇa, kṣatriya, vaiśya or śūdra, just as one is trained to become an engineer, doctor or lawyer. Those who are properly trained can be considered human beings; if one is not trained socially and spiritually—that is, if one is uneducated and unregulated—his life is on the animal platform. Among animals there is no question of spiritual advancement. Spiritual life can be attained by proper training-either by following the principles of varṇa and āśrama or by being directly trained in the bhakti school by the methods of śravaṇaṁ kīrtanaṁ viṣṇoḥ smaraṇaṁ pāda-sevanam/ arcanaṁ vandanaṁ dāsyaṁ sakhyam ātma-nivedanam (S.B.7:5:23). Without being trained, one cannot be sukṛtī, auspicious. In this verse Kṛṣṇa says that people approach Him when in distress, in need of money or when actually inquisitive to understand the Supreme Being, or the original source of everything. Some people approach Him in the pursuit of knowledge of the Absolute Truth, and others approach Him when they are distressed, like the devotee Gajendra. Others are inquisitive, like the great sages headed by Śaunaka, and others need money, like Dhruva Mahārāja. Śukadeva Gosvāmī approached the Lord when he pursued knowledge. All these great personalities thus took to the devotional service of the Supreme Personality of Godhead, Kṛṣṇa.

(Sri Caitanya Caritamrta----2:24:94-----translation and purport).

“"The potency of Lord Viṣṇu is summarized in three categories—namely the spiritual potency, the living entities and ignorance. The spiritual potency is full of knowledge; the living entities, although belonging to the spiritual potency, are subject to bewilderment; and the third energy, which is full of ignorance, is always visible in fruitive activities."
This is a quotation from the Viṣṇu Purāṇa. For an explanation, see Ādi-līlā 7.119.

(Sri Caitanya Caritamrta----2:24:308-----translation and purport).

“"Although the Supreme Personality of Godhead may be seen, glorified or remembered with an attitude of envy, He nevertheless awards the most confidential liberation, which is rarely achieved by the demigods and demons. What, then, can be said of those who are already fully engaged in devotional service to the Lord?"
This is a quotation from the Viṣṇu Purāṇa (4.15.17).

(Sri Caitanya Caritamrta----3:3:85-----translation and purport).
