This stage can be attained in the bhakti-yoga. Bhakti-yoga means one who has understood everything very perfectly. Sometimes foolish people say that "Bhakti-yoga is meant for the less intelligent class of men." But he is less intelligent. Unless one is very, very intelligent, he cannot take to Kṛṣṇa consciousness. Therefore Caitanya-caritāmṛta author says, kṛṣṇa yei bhaje sei baḍa catura: "Unless one is very intelligent, he cannot become a devotee of Kṛṣṇa." Because he knows everything.
That is stated in Bhagavad-gītā,
- brahma-bhūtaḥ prasannātmā
- na śocati na kāṅkṣati
- samaḥ sarveṣu bhūteṣu
- mad-bhaktiṁ labhate parām
- (BG 18.54)
One who is actually devotee, parām, parā-bhakti, he is already brahma-bhūta (SB 4.30.20), liberated, self-realized. Without being self-realized, nobody can attain unalloyed devotional platform. Bhakti means the platform where only liberated person can act. That is bhakti platform. Īhā yasya, those who are always working for Kṛṣṇa. Īhā, īhā means desire. Yasya, harer dāsye. Just to serve Kṛṣṇa. He has no other business.
Just like these boys and girls who have joined Kṛṣṇa consciousness movement from Europe and America, they have no other business. They are simply engaged in executing Kṛṣṇa consciousness. Īhā yasya harer dāsye. Karmaṇā, by working; manasā, thinking; vācā, by preaching. Karmaṇā manasā vācā. Because we have got three things to act. We can act with our senses, karma.
