Tyaktvā sva-dharmaṁ caraṇāmbujaṁ harer patet tato yadi bhajann apakvo 'tha (SB 1.5.17). If one by sentiments takes to Kṛṣṇa consciousness, tyaktvā sva-dharmam, giving up his own occupation, but maybe, for immature condition he may fall down, yatra kva va abhadram, what is the loss? And śāstra says and if person who is executing his religious process, sva-dharmeṇa, but he has no devotion service, what does he gain? What does he gain? Suppose a so-called brāhmaṇa or a perfect brāhmaṇa executes his religious process very perfectly, but he does not become a devotee, then what is his gain? These are the śāstric injunction.
So it is rāja-vidyā. This bhakti-yoga is the topmost educational system, and it is open for everyone. Caitanya Mahāprabhu said, pṛthivīte āche yata nagarādi-grama. (CB Antya-khaṇḍa 4.126). Does it means He wanted to make a farce? If every city, every town was to be broadcast with the Caitanya cult . . . so what is Caitanya cult? Caitanya cult means realization of Kṛṣṇa. That is Caitanya cult. Ārādhyo bhagavān vrajeśa-tanayas tad-dhāma vṛndāvanam (Caitanya-manjusa). This is Caitanya cult.
