While making the horoscope of Kṛṣṇa, Gargamuni, he said, idānīṁ kṛṣṇataṁ gataḥ. Śukla-raktas tathā pītam idānīṁ kṛṣṇataṁ gataḥ (SB 10.8.13): "Nanda Mahārāja, your son, this child, has now appeared as kṛṣṇa, blackish." Idānīṁ kṛṣṇataṁ gataḥ. "Otherwise this very child appeared in previous ages." Śukla-raktas tathā pīta: "He... Sometimes He appeared in white color, sometimes red, sometimes yellow."

So by the śāstra indication, especially in the Śrīmad-Bhāgavatam, Caitanya Mahāprabhu's incarnation is described:

kṛṣṇa-varṇaṁ tviṣākṛṣṇaṁ

saṅgopāṅgāstra-pārṣadam

yajñair saṅkīrtanair prāyair

yajanti hi sumedhasaḥ

(SB 11.5.32)

This is the most important verse indicating Caitanya Mahāprabhu as Kṛṣṇa. Kṛṣṇa-varṇam. He is in the same category. And another meaning, kṛṣṇa-varṇayati: "The incarnation of Kṛṣṇa who is always describing Kṛṣṇa or chanting Hare Kṛṣṇa." Varṇayati. But tviṣa akṛṣṇam: "But by complexion, akṛṣṇa, not black." So "not black," that may be many other colors. Then which of them I shall take? That is also stated in the śāstra. While making the horoscope of Kṛṣṇa, Gargamuni, he said, idānīṁ kṛṣṇataṁ gataḥ. Śukla-raktas tathā pītam idānīṁ kṛṣṇataṁ gataḥ (SB 10.8.13): "Nanda Mahārāja, your son, this child, has now appeared as kṛṣṇa, blackish." Idānīṁ kṛṣṇataṁ gataḥ. "Otherwise this very child appeared in previous ages." Śukla-raktas tathā pīta: "He . . . Sometimes He appeared in white color, sometimes red, sometimes yellow." This yellow color refers to Caitanya Mahāprabhu, golden color. So this is also confirmed. Not . . . If somebody says that "He is Kṛṣṇa. Why He is not blackish?" No. He appears as the devotee of Kṛṣṇa in golden color. We say, therefore, "golden avatāra."

So kṛṣṇa-varṇaṁ tviṣa akṛṣṇam saṅgopāṅgāstra-pārṣadam (SB 11.5.32). He is with His soldiers, saṅga, upāṅga, part of the part: Advaita Prabhu, Nityānanda Prabhu. Nityānanda Prabhu is directly part; Advaita Prabhu is part of the part. And astra. Caitanya Mahāprabhu also has His astra, weapon. The astra means to, I mean to say, paritrāṇāya sādhūnāṁ vināśāya ca duṣkṛtam (BG 4.8). So this astra, what is that? Saṅkīrtana. Saṅkīrtanaiḥ. Yajñaiḥ saṅkīrtanaiḥ prāyair yajanti hi (SB 11.5.32). This Hare Kṛṣṇa movement is also astra of Kṛṣṇa for killing the demons, but it is not like a . . . like a sword. It is not active. But it is astra. It is killing the demons, but in a different way. The demonic habits are being killed, demonic habits. Everyone, we can understand it how our demonic activities are being killed by this Hare Kṛṣṇa movement.
