Kṛṣṇa is describing now buddhi-yoga. Buddhi-yoga means bhakti-yoga. This, this word, buddhi-yoga . . . Buddhi means intelligence. One who is very intelligent, he can take to Kṛṣṇa consciousness. Therefore bhakti-yoga´s another name is buddhi-yoga. Buddhi-yoga. Because buddhi-yoga . . . there are many verses in the Bhagavad-gītā, you'll find. Just like Kṛṣṇa says:
- bahūnāṁ janmanām ante
- jñānavān māṁ prapadyate
- vāsudevaḥ sarvam iti
- sa mahātmā sudurlabhaḥ
- (BG 7.19)
Kṛṣṇa says, "After many, many births' endeavor . . ." Because everyone is trying to be happy. That is the struggle for existence. Why this struggle? To become happy. So sometimes they are karmīs, sometimes they are jñānīs, sometimes they are yogīs, sometimes . . . as soon as they become bhakta, that is success. But so long he is not bhakta but otherwise, karmīs, jñānīs . . . generally they are divided: karmīs, jñānīs, yogīs. Therefore Rūpa Gosvāmī has said:
- bhukti-mukti-siddhi
- piśācī yāvat hṛdi vartate
- tāvad bhakti-sukhasyātra
- katham abhyudayo bhavet
- (Brs. 1.2.22, CC Madhya 19.176)
"So long in one's heart there is a piśācī . . ." Piśācī means, what is called, a witch? Yes. The witch is there, piśācī. What is that piśācī? Bhukti-mukti-siddhi. Bhukti means karmī, to . . . one who wants to enjoy this material world by working. That is called bhukti. Bhoktā: "I want to enjoy." Everyone is trying that. Struggle for existence. Everyone is trying to . . . "I want to enjoy this material world to the fullest extent." So their struggle going on, competition. That is called bhukti. And another? Mukti. Mukti means those who are disappointed. Disappointed must be, because nobody can be happy here with this karmī plan. That is not possible.
