Bhāgavata-Māhātmya and the Complete Summary of the Śrīmad-Bhāgavatam
तस्य कर्माण्यपाराणि कीर्तितान्यसुरद्विष: । पूतनासुपय:पानं शकटोच्चाटनं शिशो: ॥ २८ ॥ तृणावर्तस्य निष्पेषस्तथैव बकवत्सयो: । अघासुरवधो धात्रा वत्सपालावगूहनम् ॥ २९ ॥
tasya karmāṇy apārāṇi kīrtitāny asura-dviṣaḥ pūtanāsu-payaḥ-pānaṁ śakaṭoccāṭanaṁ śiśoḥ
Also glorified are the countless līlās of Śrī Kṛṣṇa, the foe of the asuras: He drew out Pūtanā’s very life along with her breast milk, shattered the cart, crushed Tṛṇāvarta, slew Bakāsura and Vatsāsura, destroyed Aghāsura, and enacted the pastime that occurred when Dhātā Brahmā hid the calves and the cowherd boys in a cave.
This verse recalls that Kṛṣṇa, even as an infant, drank Pūtanā’s milk along with her life-air—showing His supreme power and that contact with Him (even inimically) brings purification and liberation-like benefit.
Because His līlā includes protecting devotees by destroying demonic forces, as illustrated by Pūtanā’s death and the destruction of the cart demon Śakaṭāsura.
By regularly hearing and chanting Kṛṣṇa’s līlās with faith—remembering that divine protection and purification arise from sincere remembrance and glorification.
