Guest (2): Has to be transferred.
Prabhupāda: To Kṛṣṇa. Yes. Mayy āsakta-manaḥ partha. This is yoga. This is bhakti-yoga.
Mr. Sar: It is said, jñānaṁ te sa-vijñānam.
Prabhupāda: But it can be done mad-āśrayaḥ. Āśrayaḥ, to take shelter. "Taking shelter of Kṛṣṇa," you can make this meaning or mad-āśrayaḥ means "one who has taken shelter of Kṛṣṇa."
