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
Ebenso werden die unzähligen līlā Śrī Kṛṣṇas, des Feindes der asura, gepriesen: wie Er Pūtanās Lebenshauch mitsamt ihrer Milch aussog, den Karren zertrümmerte, Tṛṇāvarta zermalmte, Bakāsura und Vatsāsura tötete, Aghāsura erschlug, und die līlā, als Dhātā Brahmā die Kälber und Hirtenfreunde in einer Höhle verbarg.
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.
