Any person from any part of the world may be made a brāhmaṇa by the regular process of initiation, and when he follows brahminical behavior, observing the principle of abstaining from intoxication, illicit sex, meat-eating and gambling, he may be offered sannyāsa. All the sannyāsīs in the Kṛṣṇa consciousness movement, who are preaching all over the world, are regular brāhmaṇa-sannyāsīs. Thus the so-called caste brāhmaṇas should not object to offering them respectful obeisances. By offering such obeisances, as recommended by Śrī Caitanya Mahāprabhu, they will diminish their offenses and automatically awaken to their natural position of devotional service. As it is said, nitya-siddha kṛṣṇa-prema sādhya kabhu naya: (Cc. madhya 22.107) kṛṣṇa-prema can be awakened in a purified heart. The more we offer obeisances to sannyāsīs, especially Vaiṣṇava sannyāsīs, the more we diminish our offenses and purify our hearts. Only in a purified heart can kṛṣṇa-prema awaken. This is the process of Śrī Caitanya Mahāprabhu's cult, the Kṛṣṇa consciousness movement.
(Sri Caitanya Caritamrta----1:17:266----purport).

Love of God is not an ordinary commodity. Caitanya Mahāprabhu was worshiped by Rūpa Gosvāmī because He distributed love of God, kṛṣṇa-premā, to everyone. Rūpa Gosvāmī praised Him as mahā-vadānya, a greatly munificent personality, because He was freely distributing to everyone love of Godhead, which is achieved by wise men only after many, many births. Kṛṣṇa-premā, Kṛṣṇa consciousness, is the highest gift which can be bestowed on anyone whom we presume to love.
(Srimad Bhagavatam----3:23:8----purport).

On the other hand, our relationship with Kṛṣṇa, the Supreme Personality of Godhead, is eternal. Nitya-siddha kṛṣṇa-prema. The pure souls are eternally in love with Kṛṣṇa, and this permanent love, either as a servant, a friend, a parent or a conjugal lover, is not at all difficult to revive. Especially in this age, the concession is that simply by chanting the Hare Kṛṣṇa mantra (harer nāma harer nāma harer nāmaiva kevalam (CC.1:17:21) one revives his original relationship with God and thus becomes so happy that he does not want anything material. As enunciated by Śrī Caitanya Mahāprabhu, na dhanaṁ na janaṁ na sundarīṁ kavitāṁ vā jagad-īśa kāmaye (Cc. Antya 20.29, Śikṣāṣṭaka 4). A very advanced devotee in Kṛṣṇa consciousness does not want riches, followers or possessions.
(Srimad Bhagavatam----7:7:39----purport).

However, Lord Caitanya's greatest gift was His teaching that Kṛṣṇa can be treated as one's lover. In this relationship the Lord becomes so much attached to His devotee that He expresses His inability to reciprocate. Kṛṣṇa was so obliged to the gopīs, the cowherd girls of Vṛndāvana, that He felt unable to return their love. "I cannot repay your love," He told them. "I have no more assets to give." Devotional service on this highest, most excellent platform of lover and beloved, which had never been given by any previous incarnation or ācārya, was given by Caitanya Mahāprabhu. Therefore Kṛṣṇadāsa Kavirāja, quoting Śrīla Rūpa Gosvāmī, writes in the fourth verse of his book, "Lord Caitanya is Kṛṣṇa in a yellow complexion, and He is Śacīnandana, the son of mother Śacī. He is the most charitable personality because He came to deliver kṛṣṇa-prema, unalloyed love for Kṛṣṇa, to everyone. May you always keep Him in your hearts. It will be easy to understand Kṛṣṇa through Him."
(Sri Caitanya Caritamrta--introduction).

There are millions of living entities who have become conditioned by the laws of material nature, and they are wandering throughout the planetary systems of this universe in different bodily forms. Among them, one who is fortunate meets a bona fide spiritual master by the grace of Kṛṣṇa and comes to understand the meaning of devotional service. By discharging devotional service under the direction of the bona fide spiritual master, or ācārya, he develops love of Godhead. One whose love of Godhead (kṛṣṇa-prema) is awakened and who thus becomes a devotee of the inconceivable Supreme Personality of Godhead is to be considered extremely fortunate. The Māyāvādī sannyāsīs admitted this fact to Śrī Caitanya Mahāprabhu. It is not easy for one to become a Kṛṣṇa conscious person, but by the mercy of Śrī Caitanya Mahāprabhu it can be possible, as will be proven in the course of this narration.
(Sri Caitanya Caritamrta----1:7:100----purport).

The Māyāvādī philosophers consider the highest goal of perfection to be liberation (mukti), which is the fourth perfectional platform. Generally people are aware of four principal goals of life—religiosity (dharma), economic development (artha), sense gratification (kāma) and ultimately liberation (mokṣa)—but devotional service is situated on the platform above liberation. In other words, when one is actually liberated (mukta) he can understand the meaning of love of Godhead (kṛṣṇa-prema). While teaching Rūpa Gosvāmī, Śrī Caitanya Mahāprabhu stated, koṭi-mukta-madhye "durlabha" eka kṛṣṇa-bhakta: "Out of millions of liberated persons, one may become a devotee of Lord Kṛṣṇa."
(Sri Caitanya Caritamrta----1:7:144----purport).

Śrī Caitanya Mahāprabhu, without neglecting the necessities of the body, imparted spiritual advancement to purify the existential condition of humanity. Therefore if a logician makes his judgment impartially, he will surely find that Śrī Caitanya Mahāprabhu is the mahā-vadānyāvatāra, the most magnanimous incarnation. He is even more magnanimous than Lord Kṛṣṇa Himself. Lord Kṛṣṇa demanded that one surrender unto Him, but He did not distribute love of Godhead as magnanimously as Śrī Caitanya Mahāprabhu. Therefore Śrīla Rūpa Gosvāmī offers Lord Caitanya his respectful obeisances with the words namo mahā-vadānyāya kṛṣṇa-prema-pradāya te/ kṛṣṇāya kṛṣṇa-caitanya-nāmne gaura-tviṣe namaḥ (CC.2:19:53). Lord Kṛṣṇa simply gave the Bhagavad-gītā, by which one can understand Lord Kṛṣṇa as He is, but Śrī Caitanya Mahāprabhu, who is also Kṛṣṇa Himself, gave people love of Kṛṣṇa without discrimination.
(Sri Caitanya Caritamrta----1:8:15----purport).

This is the benefit of Lord Caitanya's movement. If one somehow or other comes in contact with the Hare Kṛṣṇa movement, without consideration of his being a śūdra, vaiśya, Jagāi, Mādhāi or even lower, he becomes advanced in spiritual consciousness and immediately develops love of Godhead. We now have actual experience that throughout the entire world this movement is making many such persons lovers of God simply by the chanting of the Hare Kṛṣṇa mahā-mantra. Actually, Śrī Caitanya Mahāprabhu has appeared as the spiritual master of the entire world. He does not discriminate between offenders and the innocent. Kṛṣṇa-prema-pradāya te: (CC.2:19:53) He liberally gives love of Godhead to anyone and everyone.
(Sri Caitanya Caritamrta----1:8:21----purport).

Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura writes in his Anubhāṣya, “In the Gaura-gaṇoddeśa-dīpikā (203) it is said, "Bhāgavata Ācārya compiled a book entitled Kṛṣṇa-prema-taraṅgiṇī, and he was the most beloved devotee of Lord Caitanya Mahāprabhu." When Lord Śrī Caitanya Mahāprabhu visited Varāhanagara, now a suburb of Calcutta, He stayed in the house of a most fortunate brāhmaṇa who was a very learned scholar in Bhāgavata literature. As soon as this brāhmaṇa saw Lord Caitanya Mahāprabhu, he began to read Śrīmad-Bhāgavatam. When Mahāprabhu heard his explanation, which expounded bhakti-yoga, He immediately became unconscious in ecstasy. Lord Caitanya later said, "I have never heard such a nice explanation of Śrīmad-Bhāgavatam. I therefore designate you Bhāgavata Ācārya. Your only duty is to recite Śrīmad-Bhāgavatam. That is My injunction." His real name was Raghunātha. His monastery, which is situated in Varāhanagara, about three and a half miles north of Calcutta on the bank of the Ganges, still exists, and it is managed by the initiated disciples of the late Śrī Rāmadāsa Bābājī. Presently, however, it is not as well managed as in the presence of Bābājī Mahārāja.
(Sri Caitanya Caritamrta----1:10:113----purport).

At the conclusion of the Bhagavad-gītā, Lord Kṛṣṇa advised complete surrender unto Him, promising all protection to His devotee. Unfortunately, people are so fallen that they cannot accept the instructions of Lord Kṛṣṇa; therefore Kṛṣṇa returned with the same mission, but He executed it in a different way. As Lord Śrī Kṛṣṇa, the Supreme Personality of Godhead, He ordered us to surrender unto Himself, but as Lord Śrī Caitanya Mahāprabhu, He taught us how to surrender to Kṛṣṇa. Therefore He is praised by the Gosvāmīs: namo mahā-vadānyāya kṛṣṇa-prema-pradāye te. Lord Śrī Kṛṣṇa is certainly the Personality of Godhead, but He is not as magnanimous as Śrī Caitanya Mahāprabhu. Lord Kṛṣṇa simply gave orders for one to become His devotee (man-manā bhava mad-bhaktaḥ), but Śrī Caitanya Mahāprabhu actually taught the process of Kṛṣṇa consciousness. If one wants to become a devotee of Kṛṣṇa, he must first take shelter of the lotus feet of Śrī Caitanya Mahāprabhu, following in the footsteps of Sārvabhauma Bhaṭṭācārya and other exalted devotees.
(Sri Caitanya Caritamrta----2:6:255----purport).

However, Lord Caitanya's greatest gift was His teaching that Kṛṣṇa can be treated as one's lover. In this relationship the Lord becomes so much attached to His devotee that He expresses His inability to reciprocate. Kṛṣṇa was so obliged to the gopīs, the cowherd girls of Vṛndāvana, that He felt unable to return their love. "I cannot repay your love," He told them. "I have no more assets to give." Devotional service on this highest, most excellent platform of lover and beloved, which had never been given by any previous incarnation or ācārya, was given by Caitanya Mahāprabhu.

It will be easy to understand Kṛṣṇa through Him."
