Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 43

Sanskrit:

नन्द: स्वपुत्रमादाय प्रेत्यागतमुदारधी: ।मूर्ध्न्युपाघ्राय परमां मुदं लेभे कुरूद्वह ॥ ४३ ॥

ITRANS:

nandaḥ sva-putram ādāyapretyāgatam udāra-dhīḥmūrdhny upāghrāya paramāṁmudaṁ lebhe kurūdvaha

Translation:

O Mahārāja Parīkṣit, best of the Kurus, Nanda Mahārāja was very liberal and simple. He immediately took his son Kṛṣṇa on his lap as if Kṛṣṇa had returned from death, and by formally smelling his son’s head, Nanda Mahārāja undoubtedly enjoyed transcendental bliss.

Purport:

Nanda Mahārāja could not understand how the inhabitants of his house had allowed Pūtanā to enter the house, nor could he imagine the gravity of the situation. He did not understand that Kṛṣṇa had wanted to kill Pūtanā and that His pastimes were performed by Yoga-māyā. Nanda Mahārāja simply thought that someone had entered his house and created havoc. This was Nanda Mahārāja’s simplicity.
