Also glorified are the innumerable pastimes of Śrī Kṛṣṇa, the enemy of the demons, including His childhood pastimes of sucking out Pūtanā’s life air along with her breast milk, breaking the cart, trampling down Tṛṇāvarta, killing Bakāsura, Vatsāsura and Aghāsura, and the pastimes He enacted when Lord Brahmā hid His calves and cowherd boyfriends in a cave.
