Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 4

Sanskrit:

तोकेनामीलिताक्षेण पूतनाया महौजस:। पीत: स्तन: सह प्राणै: कालेनेव वयस्तनो: ॥ ४ ॥

ITRANS:

tokenāmīlitākṣeṇapūtanāyā mahaujasaḥpītaḥ stanaḥ saha prāṇaiḥkāleneva vayas tanoḥ

Translation:

As a mere infant who had hardly yet opened His eyes, He drank the breast milk of the powerful demoness Pūtanā and then sucked out her very life air as well, just as the force of time sucks out the youth of one’s body.

Purport:

The word vayaḥ in this verse indicates youth or life span in general. With irresistible power, time takes away our life, and that time is actually Lord Kṛṣṇa Himself. Thus in the case of the powerful witch Pūtanā, Lord Kṛṣṇa accelerated the time process and within an instant withdrew the duration of her life. Here the cowherd men mean to say, “How could a mere infant who could barely open His eyes so easily kill a very powerful demoness?”
