That Hari-bhakti-vilāsa is written by Sanātana Gosvāmī in the name of Gopāla Bhaṭṭa Gosvāmī. Because Gopāla Bhaṭṭa Gosvāmī was very young boy, and Rūpa Gosvāmī and Sanātana Gosvāmī, they were very elderly. But because all the six Gosvāmīs happened to be direct disciples of Lord Caitanya, so Gopāla Bhaṭṭa Gosvāmī, although very young, he was treated as younger brother of Sanātana Gosvāmī. So this book was actually written by Sanātana Gosvāmī, but it was published, or dedicated to, Gopāla Bhaṭṭa Gosvāmī.
In this book the rules and regulation of the Vaiṣṇavas are described—of the brahmacārīs, the students; of the gṛhasthas, householders; vānaprastha, retired men; and sannyāsī, renounced order—how gṛhastha should live, how brahmacārī should live, how vānaprastha should live, how sannyāsī should live. All the . . . it is called Vaiṣṇava smṛti.
Śruti and smṛti. Śruti means Vedic literature, which is traditionally, from time immemorial, it is learned simply by hearing from authoritative sources. Just like in the Śrīmad-Bhāgavatam in the First Canto, first verse, it is said, tene brahma hṛdā Adi-kavaye (SB 1.1.1). The original authority of Vedic literature, Lord Brahmā, he was instructed about Vedic knowledge by Lord Kṛṣṇa. And he imparted Vedic knowledge to the world. So he was the first creature, living creature, after creation. So there was nobody to give him initiation, because he is the only living creature at that time. So the Lord Himself initiated.
How He initiated? Hṛdā, through the heart. Because He is situated in everyone's heart. Īśvaraḥ sarva-bhūtānāṁ hṛd-deśe 'rjuna tiṣṭhati (BG 18.61). He is . . . the Lord is seated in everyone's heart. So he initiated. Tene brahma hṛdā. Hṛdā means "through the heart." And that is also confirmed in the Bhagavad-gītā, that buddhi-yogaṁ dadāmi tam: "I give instruction, buddhi-yogam, the yoga principle of intelligence, or bhakti-yoga." Whom? Teṣāṁ satata-yuktānāṁ bhajatāṁ prīti-pūrvakam (BG 10.10): One who is engaged with love and affection in devotional service, to him He gives instruction. Not to all. Samo 'haṁ sarva-bhūteṣu (BG 9.29). God is equal to everyone.
