Kāla, time, is very powerful. Time . . . in time everything can be done. In time you can become very happy, and in time you can become very distressed, very much distressed, unhappy. Time can give you. And time is also Kṛṣṇa, kāla-rūpeṇa. When . . . you'll find in the Bhagavad-gītā that, in the Eleventh Chapter . . . I've just now forget that . . . that, "Who are You?" Kāla. The virāḍ-rūpa, the universal form seeing, Arjuna said, "Who are You, Sir?" So He said that, "I am in the kāla-rūpa, in the form of time now. I have come to kill the all, all of you."
So therefore our business should be that this life should be utilized only for complete Kṛṣṇa consciousness. No other business. That is Caitanya Mahāprabhu's cult. And it is not very difficult, not at all difficult. Kīrtanīyaḥ sadā hariḥ (CC Adi 17.31). But it is difficult. It is very difficult to chant Hare Kṛṣṇa mantra twenty-four hours. Those who are not accustomed, they'll become mad simply by chanting.
