First of all you have to come to the stage of tranquillity. Prasanna-manasa. Evaṁ prasanna-manasaḥ. Prasanna-manasa means always jubilant. That is . . . that can be achieved by this process: bhagavad-bhakti-yogataḥ, by devotional service, no by no other process. Evaṁ prasanna-manaso bhagavad-bhakti-yogataḥ (SB 1.2.20). One can be jubilant only by practicing bhagavad-bhakti-yoga.
There are many other yoga system—karma-yoga, jñāna-yoga, dhyāna-yoga, haṭha-yoga. Everything you endeavor for spiritual enlightenment, that is called yoga. So there are different types of yoga, but real yoga is bhagavad-bhakti, devotional service. Therefore in the Bhagavad-gītā it is said, yoginām api sarveṣām: "Of all the yogīs . . ." There are different types of yoga system and different types of yogīs also. But Kṛṣṇa says, "Of all the yogīs . . ."
- yoginām api sarveṣāṁ
- mad-gatenāntar-ātmanā
- śraddhāvān bhajate yo māṁ
- sa me yuktatamo mataḥ
- (BG 6.47)
"That yogī who is devotee and always thinking of Me, or thinking of Kṛṣṇa within the heart . . ." Yoginām api sarveṣāṁ mad-gatenāntar-ātmanā, śraddhāvān, faithful; bhajate. This is bhajana: Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare. So he is first-class yogī who is chanting Hare Kṛṣṇa mantra and thinking of Kṛṣṇa within his heart, first-class yogī. That is bhagavad-bhakti-yoga. And if he does it nicely, according to the rules and regulation, in the beginning, then he becomes prasanna-manasa, prasanna-manasa, enlightened, engladdened. There is no more any lamentation or hankering. This is the sign.
