So we have to accept the form of the Lord as confirmed in the śāstra and as confirmed by the ācārya. Then it is perfect. Sādhu śāstra guru vākya tinete kariyā aikya. We have to understand something very rigidly by three things, the... It must be confirmed by the śāstra, and it must be confirmed by the ācāryas and by the spiritual master. Very simple thing. We have description of Kṛṣṇa in the śāstra, Brahma-saṁhitā, the treatise given by Lord Brahma. And this Brahma-saṁhitā was collected from South India in handwriting by Caitanya Mahāprabhu and He delivered to His devotees. So the sādhu... Caitanya Mahāprabhu is Kṛṣṇa. Still, He is playing the part of a sādhu. Sādhu and śāstra, Brahma-saṁhitā, and because we have received from Caitanya Mahāprabhu, we are delivering to our disciples: "Here is Kṛṣṇa's form." The sādhu, śāstra, guru. It must be confirmed. Then we can accept, not that whimsically if some rascal comes and becomes God by concoction. We cannot accept. It must be confirmed by... (aside:) Why do you bother? Let them. No, no. As he likes. That's all.
So sādhu śāstra guru. This is the way. When Caitanya Mahāprabhu was instructing Sanātana Gosvāmī in various subject matter, and He also described the incarnation in Kali-yuga from śāstra that,
- kṛṣṇa-varṇam tviṣākṛṣṇaṁ
- sāṅgopāṅgāstra-pārṣadam
- yajñaiḥ saṅkīrtanaiḥ-prāyair
- yajanti hi su-medhasaḥ
- (SB 11.5.32)
He quoted from Bhāgavatam, "This is the incarnation of Kali-yuga." So He is Himself yajñaiḥ saṅkīrtanaiḥ-prāyaiḥ. So Sanātana Gosvāmī was prime minister, very intelligent man. So he had inquired from Caitanya Mahāprabhu that "How we can accept the avatāra?" So Caitanya Mahāprabhu also said, "From the śāstra." And Sanātana Gosvāmī got it confirmed that Caitanya Mahāprabhu was... He stopped, of course. When he inquired that "Shall I accept this personality who is now preaching saṅkīrtana movement and along with His associates, He is the Supreme Lord?" Then Caitanya Mahāprabhu said, "Let us go on further. We don't..."
So this is the way, not whimsically accept any rascal as avatāra. No. That is not the process. Or any rascal as God. This rascaldom has killed the whole human society to become atheist. You should be very, very careful of these rascals. As soon as somebody says that "I am God," you shall immediately take him as dog, not God. So God is not so cheap. In the Brahma-saṁhitā the description of God, Kṛṣṇa, is given, and it is said there,
- yasyaika-niśvasita-kālam athāvalambya
- jīvanti loma-bilajā jagad-aṇḍa-nāthāḥ
- viṣṇur mahān sa iha yasya kalā-viśeṣo
- govindam ādi-puruṣaṁ tam ahaṁ bhajāmi
- (Bs. 5.48)
