Yogi Amrit Desai: Bhakti. No matter what path you follow, without bhakti it is incomplete.
Prabhupāda: So you cannot go to God...
Yogi Amrit Desai: No, without bhakti, no.
Prabhupāda: No. Bhaktyā mām abhijānāti (BG 18.55). Kṛṣṇa never says, "By karma, jñāna, yoga one can achieve Me." Bhaktyā mām abhijānāti yāvān yaś cāsmi tattvataḥ. So unless you take to bhakti, a little advancement it may be, but that is material.
Yogi Amrit Desai: It's not of the highest nature.
Prabhupāda: So you can take... You have taken to bhakti-yoga, but take it seriously, pure bhakti-yoga. Anyābhilāṣitā-śūnyaṁ jñāna-karmādy-anāvṛtam (Brs. 1.1.11). (break) ...favorable, according to bhakti-yoga, then he is successful.
Trivikrama: Śīlanaṁ bhaktir uttamā.
Yogi Amrit Desai: Pure bhakti. (Hindi) jñāna...
Prabhupāda: (Hindi) Kevala-bodha-labdhaye, kliśyanti. Just to know things, if he's simply troubling, his gain is that troubling only. Śreyaḥ-sṛtiṁ bhaktim udasya kliśyanti ye kevala-bodha-labdhaye. So jñāna... This jñāna is to understand. Just like the scientists, they are getting some knowledge, studying some features, and what do they gain more?
Yogi Amrit Desai: Just information and a memory.
