So renouncement, simply giving up something, is not very good idea. You must have something better. Paraṁ dṛṣṭvā nivartate (BG 2.59). If you get something better, then you give up something inferior. Our Vaiṣṇava philosophy, renouncement means renouncement of sense gratification. The Māyāvāda sannyāsa means karma-tyāga, simply reading Vedānta philosophy, sāṅkhya philosophy, and everything given up. But our Vaiṣṇava philosophy is giving up the wrong thing and accepting the right thing—side by side.
Simply if I give up, it will not stay very long time. If I simply by sentiment give up, brahma satyaṁ jagan mithyā, "This world is false and Brahman is the real, reality," so there are so many sannyāsīs we see, they give up the so-called mithyā world and come to the Brahman realization by meditation. By meditation, meditation . . . then meditation means hospital and school. Because there is no Brahman, there is no reality. So after much meditation, comes to the conclusion that, "Now I am a sannyāsī. I must open school, college and daridra-nārāyaṇa sevā and goat-nārāyaṇa killing." This kind of sannyāsa has no meaning. Daridra-nārāyaṇa sevā, by killing goat nārāyaṇa. Goat is not Nārāyaṇa; simply daridras are Nārāyaṇa. If you accept one as Nārāyaṇa, why should you not accept the other as Nārāyaṇa?
So this kind of false sannyāsa is not accepted by the Vaiṣṇavas. Vaiṣṇavas, they accept sannyāsa for better activities. For better activities means dedicated life for satisfying the Supreme Lord. Mām ekaṁ śaraṇaṁ vraja. Anyone who has sacrificed his life for Kṛṣṇa, he's sannyāsa. That is stated in the Bhagavad-gītā: anāśritaḥ karma-phalaṁ kāryaṁ karma karoti yaḥ, sa sannyāsī (BG 6.1). Na niragnir na cākriyaḥ. One who has given up . . . a sannyāsī is not supposed to cook. Ni . . . niragniḥ. And na niragnir na yogī. But anāśritaḥ karma-phalam.
Tyāgī means karma-phala tyāga. This is tyāga, real tyāga. Suppose you are working. You are doing some business and getting lakhs of rupees' profit. If you can give up that profit for Kṛṣṇa, that is sannyāsa. Otherwise, "I shall enjoy fully the profit and I have become a great devotee"? No. Sannyāsa means, as it is stated, anāśritaḥ karma-phalaṁ. Karma-phalaṁ. There must be some karma-phala, whatever you do. There must be some result, bad or good.
So anāśritaḥ, without taking shelter of the result of activities, kāryaṁ karma karo . . . "It is my duty." Just like Arjuna did. Arjuna understood that Kṛṣṇa wanted the fight. He took it, kāryam, that "I, this, this, I must do. This I must do. Kṛṣṇa wants it. Because my business is to satisfy Kṛṣṇa. I cannot become nonviolent, as I wanted to become falsely, 'Kṛṣṇa, I don't want to fight with my cousin-brothers, my nephews, my grandfather.' That was my sense gratification."
