If we undergo this tapasya, then our existence will be purified. This is . . . This method, this process, is devotional service. The devotional service, from the very beginning it is transcendental. Īhā yasya harer dāsye. If you simply desire to serve Kṛṣṇa, that is the beginning of existentional purification, immediately. Īhā yasya harer dāsye karmaṇā manasā vāca (Bhakti-rasāmṛta-sindhu 1.2.187). Simply if you sincerely think that "How shall I serve Kṛṣṇa?" "Kṛṣṇa" does not mean simply Kṛṣṇa. "Kṛṣṇa" means Kṛṣṇa, Kṛṣṇa's name, Kṛṣṇa's form, Kṛṣṇa's quality, Kṛṣṇa's paraphernalia, Kṛṣṇa's association—everything in connection. Nirbandhe kṛṣṇa-sambandha yukta vairāgyam ucyate (Bhakti-rasāmṛta-sindhu 1.2.255). Everything.
So in this way if we lead our life, then this life will be successful, and then the result will be yasmād brahma-saukhyam. Brahma-saukhyam. Here brahma-saukhyam may be interpreted, as Māyāvādī says, brahma-sukha, brahma-līna. This is also brahma-līna, brahma-sukha, but it is not the Māyāvādī philosophy. Māyāvādī philosophy is to kill himself; to become one with Brahman. So if . . . suppose I have to eat something to enjoy. So I can eat. That is enjoyment. But if I lose my existence, I become the food, then where is enjoyment? No. The enjoyment is: "The food is there; I am there. I shall eat and enjoy." That means dvaita. Monism is not enjoyment, and therefore they fall down: āruhya kṛcchreṇa paraṁ padaṁ tataḥ patanty adho (SB 10.2.32). Brahma-sukha, do not think that to become Brahman or to become one with Brahman . . . That is not sukha. That they do not know. Therefore, my Guru Mahārāja used to say, a poor fund of knowledge. By becoming one with the Brahman, Supreme Brahman, that is not actually sukha. If it is actually sukha, then why in the śāstra it is said, āruhya kṛcchreṇa paraṁ padaṁ tataḥ patanty adho (SB 10.2.32)? By very severe austerities they come to the Brahman platform, monism, to become one with the Supreme, but from there he falls down. Why falls down? Anādṛta-yuṣmad-aṅghrayaḥ. Because they have no information of the shelter of the lotus feet of the Lord. Unless you come to that point, then there is no possibility of eternal happiness.
