“The guru, as specified by Caitanya Mahāprabhu, that is not very difficult, who is guru. Caitanya Mahāprabhu said,āmāra ājñāya guru hañā tāra’ ei deśayāre dekha, tāre kaha ‘kṛṣṇa’-upadeśa(CC Madhya 7.128)
He is guru. One who is strictly following the instruction of Caitanya Mahāprabhu, and after following Him, he is just delivering the instruction as Kṛṣṇa has said, then you become guru. It is not difficult. Caitanya Mahāprabhu has ordered everyone. Therefore our process is to follow Caitanya Mahāprabhu, and then try to understand Kṛṣṇa’s instruction.”
