First of all, one must prove that he's trustworthy; then we can accept him as trustworthy. Our mind is not fixed up; very restless. Cañcalaṁ hi manaḥ kṛṣṇa pramāthi balavad dṛḍham (BG 6.34). This is right example. Just like Haridāsa Ṭhākura. He was competent enough, mukta-puruṣa, but still, he was chanting regularly 300,000 times Hare Kṛṣṇa mahā-mantra. Even Caitanya Mahāprabhu said that "Now you have become old man. You can reduce the number." Saṅkhyā-pūrvaka-nāma-gāna-natibhiḥ kālāvasānī-kṛtau nidrāhāra-vihārakādi-vijitau cātyanta-dīnau ca yau vande rūpa-sanātanau raghu-yugau śrī-jīva-gopālakau (Sad-gosvamy-astaka 6). Raghunātha dāsa Gosvāmī especially, he was very strict in the matter of following the regulative principles. Raghunātha dāsa Goswami, he was living in Rādhā-kuṇḍa. He was very rich man's son and practiced very rigidly vairāgya.
Bhakti-yoga means vairāgya. As far as possible to deny material necessities, that is vairāgya. It is called vairāgya-vidyā. Śrīla Sārvabhauma Bhaṭṭācārya has said, vairāgya-vidyā-nija-bhakti-yogam (CC Madhya 6.254). Vairāgya-vidyā. Bhakti-yoga means vairāgya. Bhaktiḥ pareśānubhavo viraktir anyatra syāt (SB 11.2.42). This is bhakti-yoga: no more any necessity for material things. Niṣkiñcinasya bhagavad-bhajanonmukhasya. There are so many. Rūpa Gosvāmī, Sanātana Gosvāmī, they were liberated persons. Even Caitanya Mahāprabhu, He is God Himself, but still, to teach us, He was observing the regulative principles of a sannyāsī very, very strictly. These things, to teach us . . . Similarly, Haridāsa Ṭhākura, he's called Brahma-Haridāsa. Sometimes he is called Yavana-Haridāsa. Yavana means Muslim or those who are not in the Vedic principles, yavana, mleccha. Just like we have seen some temples, our foreign devotees are not allowed, because they have got the rules that mlecchas and yavanas, because they are very unclean, they should not be allowed. But that should not be applicable to the devotees of this Kṛṣṇa consciousness movement, because they have learned how to remain clean, how to follow the . . . At least, they are expected. They promised at the time of initiation, "Yes, I shall not do this. I shall not do this." So if he's actually following the rules and regulations, he is no more unclean—simply by chanting.
