There are fixed colors for the Supreme Personality of Godhead. Śukla, śuklo raktas tathā pīta idānīṁ kṛṣṇatāṁ gataḥ. When Kṛṣṇa was born at Nanda Mahārāja's place, or Kṛṣṇa appeared, then . . . so according to Vedic system there is jāta-karma. As soon as child is born, immediately horoscope is made, and according to horoscope his name is given. There are daśa-karma. Daśa-karma. So one of these is at the birth, that before the child is begotten, there is one saṁskāra, garbhādhāna-saṁskāra. Similarly, after the child is born, then another saṁskāra, jāta-karma-saṁskāra. So there are so many saṁskāras. Saṁskārād bhaved dvijaḥ: By following the saṁskāra, purificatory process, one becomes brāhmaṇa: the upanayana-saṁskāra, the sacred thread saṁskāra.
So when Kṛṣṇa was having the jāta-karma-saṁskāra by Gargamuni, the priest of Vasudeva . . . He was sent to Nanda Mahārāja to perform the Kṛṣṇa's jāta-karma. So he was a learned astrologer. He said, "Nanda Mahārāja, your this son formerly had three other colors." Śuklo raktas tathā pīta. "He was of white color, He was of red color, He was of yellow color." Idānīṁ kṛṣṇatāṁ gataḥ. "Now He has appeared in blackish color." Idānīṁ kṛṣṇatāṁ gataḥ. So kṛṣṇa-varṇaṁ tviṣākṛṣṇam (SB 11.5.32). Tviṣā means by complexion He is not black. Then He must be either of the three—white, red and yellow.
So Caitanya Mahāprabhu's color is yellowish golden color. Therefore it is said: "He is Kṛṣṇa, but now He has appeared in golden complexion." Kṛṣṇa-varṇaṁ tviṣā akṛṣṇam. And sāṅgopāṅgāstra-pārṣadam: "He is always surrounded by His associates." Aṅga, upāṅga. Aṅga means personal, and upāṅga means expansion of the expansion, which is called kalā. The first expansion is called avatāra, and when there is another avatāra from avatāra, that is called kalā. Rāmādi-mūrtiṣu kalā-niyamena tiṣṭhan (Bs. 5.39). There is scientific analysis in the śāstra. Not that any rascal comes, "I am God." This is not acceptable. We have to understand śāstra-vidhi, as śāstra it is said.
So about Śrī Cai . . . because Śrī Caitanya Mahāprabhu appeared, the Supreme Personality of Godhead, so many rascals have imitated: "Well, this Nimāi Paṇḍita, if He can become avatāra, then why not GadadharPaṇḍita?" This Ramakrishna, his name was Gadadhar Chatterjee. So he was also imitation of Caitanya Mahāprabhu. Where is the reference in the śāstra? So far Caitanya Mahāprabhu is concerned, there are so many innumerable references, in Mahābhārata, in Bhāgavata, in Purāṇa, in Upaniṣad. Therefore we accept Him as the Supreme Personality of Godhead. Not by rascal's vote, that "Let us vote this man is God; then he becomes."
