Prabhupāda: That is the beginning. That is the beginning. That is also bhakti. But bhakti means he must be conscious that "Kṛṣṇa is my Lord. I have to serve Him." That is the beginning of bhakti.
Dr. Patel: If he is not conscious, how can he do work for Him?
Prabhupāda: Yes. That is the beginning. Then it becomes purified more and more and more and more by service. Sevonmukhe hi jihvādau (Brs. 1.2.234). Then he realizes his position. Svayam eva sphuraty... The more he advances in sevonmukha, by service, God becomes revealed to him. And then buddhi-yogaṁ dadāmi tam. Then as he becomes more confidential, then he is imparted buddhi-yogam, means bhakti-yoga. What is that bhakti-yoga? Yena mām upayānti te. "That bhakti-yoga, by which he can come back to Me." Not that bhakti-yoga means you remain here in this rotten place. Yena mām upayānti te. Teṣāṁ satata-yuktānāṁ bhajatāṁ prīti-pūrvakam, buddhi-yogaṁ dadāmi tam (BG 10.10). He can receive that buddhi-yoga. What is that buddhi-yoga? Yena mām upayānti. So this is required. This is the ultimate goal of life.
