Pravrtti means here in this material world, anyone who has come, beginning from Lord Brahmā down to the small ant, they have come on account of pravṛtti, means for enjoying sense. This is material world. So long one will be engaged in sense enjoyment in different varieties, he will have to remain within this material world. Kṛṣṇa is so kind. We wanted to enjoy this material world; therefore He has given us full chance: "Yes, you enjoy." Kṛṣṇa does not want that you should enjoy this material world. That is not He . . . sometimes the foolish men, they say that "Kṛṣṇa has given us this facility for sense enjoyment. Why we shall not take it up?" Sometimes the so-called ṛṣis and yogīs, they also say, "Yes, when you have got the senses, it is meant for enjoyment. Why it should be stopped?" Yes. Really it has to be stopped. If you want real life of eternal enjoyment, then you have to stop. If you don't stop, then you remain here.
Bhūtvā bhūtvā pralīyate (BG 8.19). You have to take birth according to your desire, either as Brahmā or as ant, as a cat, as a dog, as demigod, and according to your capacity, Kṛṣṇa will give you: "All right." Ye yathā māṁ prapadyante tāṁs tathaiva bhajāmy aham (BG 4.11). If you want from Kṛṣṇa sense enjoyment, He will give you all facilities.
