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.
Prabhupāda: They cannot give any real position. They are studying so many molecules, so many atoms, so many this, so many... They are mixing... They are... That is already going on. How it is going on? Who has set up the machine going on? That they do not know.
Yogi Amrit Desai: Right. They don't know the key part of it.
Prabhupāda: Neither they can set up similar arrangement. They're simply studying.
