Nyone who is not interested in perfect life, they'll be allured by this so-called demigod worship. Antavat tu phalam. But those who are intelligent... These are the activities of the alpa-medhasaḥ, but one who is su-medhasaḥ, su-medhasaḥ, one who has got good brain substance, for him, in this age, it is recommended, yajñaiḥ saṅkīrtana-prāyair yajanti hi su-medhasaḥ.
- kṛṣṇa-varṇaṁ tviṣākṛṣṇaṁ
- sāṅgopāṅgāstra-pārṣadam
- yajñaiḥ saṅkīrtana-prāyair
- yajanti hi su-medhasaḥ
- (SB 11.5.32)
Kṛṣṇa-varṇam. Kṛṣṇa Himself. Kṛṣṇa, or kṛṣṇaṁ varṇayati. The one, the incarnation of God, who will chant always "Kṛṣṇa." That is Caitanya Mahāprabhu. Caitanya Mahāprabhu preached this Hare Kṛṣṇa mantra. Therefore kṛṣṇaṁ varṇayati, iti kṛṣṇa-varṇam. Kṛṣṇa-varṇaṁ tviṣā akṛṣṇam. Tviṣā, by complexion, He's akṛṣṇa, not kṛṣṇa, not black. Kṛṣṇa appeared blackish. Not blackish as we imagine. Kandarpa-koṭi-kamanīya. Kṛṣṇa, although He's blackish, He is attractive more than millions of Cupids. Kandarpa-koṭi-kamanīya-viśeṣa-śobhaṁ govindam ādi-puruṣaṁ tam ahaṁ bhajāmi (Bs. 5.30).
So anyway, Kṛṣṇa appears in four colors—red, black, yellow, and white—in different ages. So in this age, Kali Yuga, Kṛṣṇa appears as Caitanya Mahāprabhu, yellow color.
