Their business was, these Gosvāmīs, kṛṣṇotkīrtana-gāna-nartana-parau: they were always engaged in chanting "Kṛṣṇa." That is the real purpose of human life, especially in this age. It is stated in Śrīmad-Bhāgavatam to Parīkṣit Mahārāja by Śukadeva Goswami, he described the symptoms of Kali-yuga: it is very, very faulty. But he concluded that kalau doṣa-nidhe rājann asti hy eko mahān guṇaḥ. In this age of Kali it is very fallen age, mandāḥ sumanda-matayo manda-bhāgyā hy upadrutāḥ (SB 1.1.10). The population in this age, they are, almost all of them, are manda—manda means bad or very slow—so they do not understand what is the aim of life, or very slow to understand; therefore they are called manda. And because they do not understand their real interest of life, they can be called very bad, manda. So these are the symptoms: mandāḥ sumanda-matayo manda-bhāgyā hy upadrutāḥ.
So in this age, although it is so fallen, the śāstra says, doṣa-nidhe rājann. Kalau doṣa-nidhe rājann asti hy eko mahān guṇaḥ. There is one great opportunity. What is that opportunity? Kīrtanād eva kṛṣṇasya mukta-saṅgaḥ paraṁ vrajet (SB 12.3.51): if one takes to chanting this Hare Kṛṣṇa mantra, then he becomes relieved or freed from the all contamination of this age, and paraṁ mukta-saṅgaḥ, he becomes liberated and he goes back to home, back to Godhead, simply by chanting.
