CC Ādi 12.66
sei jale jīye śākhā, — phula-phala pāya
The Advaita Ācārya branch received the water supplied by the original gardener, Śrī Caitanya Mahāprabhu. In this way, the subbranches were nourished, and their fruits and flowers grew luxuriantly.
The branches of Advaita Ācārya nourished by the water (jala) supplied by Sri Caitanya Mahāprabhu are to be considered bona fide ācāryas. As we have discussed hereinbefore, the representatives of Advaita Ācārya later divided into two groups — the bona fide branches of the ācārya’s disciplic succession and the pretentious branches of Advaita Ācārya. Those who followed the principles of Caitanya Mahāprabhu flourished, whereas the others, who are mentioned below in the sixty-seventh verse, dried up.
