kṛṣṇam matvārbhakaṁ yan naḥ
pṛcchati śreya ātmanaḥ
Śrīla Jīva Gosvāmī relates Nārada’s thoughts: Śrī Nārada understood how Vasudeva, in line with his mood of pretending to be an ordinary householder, asked the sages about karma-yoga, although he had already attained spiritual goals even great yogīs and ṛṣis cannot achieve. But Nārada was still concerned that Vasudeva might create an awkward mood by treating Lord Kṛṣṇa as a mere child in the presence of all the sages. Nārada and the other sages felt obliged to maintain their attitude of reverence toward Lord Kṛṣṇa, so how could they ignore Him and presume to answer Vasudeva themselves? To avoid this embarrassment, Nārada took this opportunity to remind everyone present of Śrī Kṛṣṇa’s absolute supremacy.
