Somebody . . . the question is asked, "Why Kṛṣṇa created this material energy, which is so miserable condition?" Duḥkhālayam aśāśvatam (BG 8.15). So it is not Kṛṣṇa willingly created, but He gave the chance to the living entities who forgot Kṛṣṇa. He forgot Kṛṣṇa's service and wanted to enjoy this material world. Indriya-tarpaṇa. Indriya-prītaye. Nūnaṁ pramattaḥ kurute vikarma (SB 5.5.4). Here they are doing just against the law, kurute vikarma. Karma, vikarma and akarma. So we have very good experience, especially in big, big cities: people, just to get money, they are doing so many unlawful activities, vikarma. That is vikarma. They know that, "If I do this, it is punishable by law," but still, for getting money they do that. That is the nature of this material world. For sense gratification one can do anything, risking life also. The thief is stealing stealthily, hiding, and risking life to get some money. Why money? The money will supply his sense gratification.
Therefore, when one is after sense gratification, he is mad, he becomes mad. Balavān indriya-grāma durdānta. Indriya-grāma, these are the adjectives. Durdānta indriya-kāla-sarpa-paṭalī (from Caitanya-candrāmṛta 5). These are the description. Indriya, the senses, are just like snakes, kāla-sarpa-paṭalī. As the snake, as soon as it bites, immediately there is death, so similarly our indriyas, the material senses, are like durdānta indriya-kāla-sarpa-paṭalī, and we are using it. These sense are being used in this material world. Therefore it is said, nūnaṁ pramattaḥ. They have become mad, mad after sense gratification. The sublime sense gratification is sex.
