Gaura-tattva.
The most auspicious day Gaura Purnima, appearance day of Sri Caitanya Mahaprabu. In the age of Kali, Krishna appears in a golden form, chanting the two syllables krs-na. He descends along with His weapons, limbs, saktis, and eternal confidential associates. Those with intelligence worship Him with the sankirtana yajna. (Bhag. 11.5.32)
