Somehow or other, Kṛṣṇa, if we get Kṛṣṇa arisen in our heart . . . Sa vai manaḥ-kṛṣṇa-padāravindayoḥ (SB 9.4.18). If we simply concentrate our mind, that is real meditation, to think of Kṛṣṇa—man-manā bhava mad-bhakto mad-yājī māṁ namaskuru (BG 18.65). Then everything will be cleansed automatically. Kṛṣṇa says in the . . .
- śṛṇvatāṁ sva-kathāḥ kṛṣṇaḥ
- puṇya-śravaṇa-kīrtanaḥ
- hṛdy antaḥ stho hy abhadrāṇi
- vidhunoti suhṛt satām
- (SB 1.2.17)
Kṛṣṇa is there already, just like friend. Kṛṣṇa is always ready to give us instruction so that we can get out of this miserable condition of life. Kṛṣṇa is ready. He is coming to give you instruction. Simply you have to follow; then everything will be all right.
So this is the only way. Otherwise in this age, severe austerity, tapasya, celibacy, charity and so on, recommended. Tyāgena satya-śaucābhyāṁ yamena niyamena vā (SB 6.1.13). These are the methods, gradual process of transcendental life. But in this age, especially in this Kali-yuga, it is very, very difficult, almost impossible. So best thing is take to this Kṛṣṇa consciousness, kevalayā bhaktyā, simply this understanding, that "Kṛṣṇa is my eternal master; I am Kṛṣṇa's eternal servant. So let us exchange our feelings of master and servant. Then I shall be perfect."
