Su-sukhaṁ kartum. Kartum: to execute this devotional service is very pleasure. Pleasure. And avyayam: whatever you do, that is your permanent asset. It will never be lost. Bhakti-yoga process, if you can execute one percent, oh, it becomes asset, and next life you are guaranteed, because you will be given the facility of executing bhakti-yoga further. That is stated in the Bhagavad-gītā, in every śāstra. Śucīnāṁ śrīmatāṁ gehe yoga-bhraṣṭo sañjayate (BG 6.41). One who could not prosecute . . . there is other, other passages in Śrīmad-Bhāgavatam also.
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.
So one who is engaged in Kṛṣṇa consciousness, does he remain a yavana, a śūdra? What is this nonsense? But this against propaganda going on against this Kṛṣṇa consciousness movement, that "Swami Bhaktivedanta is giving sannyāsa to the yavanas, to the mlecchas," what is this rascaldom? Can yavana be sannyāsa? Can yavana become a devotee? No. Vaiṣṇave jāti-buddhir, arcye śilā-dhīr guruṣu nara-matir vaiṣṇave jāti-buddhir (Padma Purāṇa). The most obnoxious thing, most obnoxious.
They all fools, I can challenge. In Hyderabad, so many caste brāhmaṇas came to challenge me, the caste brāhmaṇa. No. No caste brāhmaṇas. Caste brāhmaṇa . . . brāhmaṇa means catur varṇyaṁ mayā sṛṣṭaṁ guṇa-karma-vibhāgaśaḥ (BG 4.13). Śrīdhara Swami says, "Yes." It is exactly to the point of śāstra. Otherwise it is not possible to make them so perfect.
