It is significant that text 24 states, catur-bhujaṁ rocamānam: “The Lord was seen in the beauty of His four-armed form.” Throughout this great work, we find Lord Kṛṣṇa manifesting His various transcendental forms, most prominently the two-armed form of Kṛṣṇa and the four-armed form of Nārāyaṇa or Viṣṇu. Thus there is no doubt that Kṛṣṇa and Viṣṇu are nondifferent, or that Kṛṣṇa is the original form of the Lord. These things are sometimes misunderstood, but the great ācāryas, experts in spiritual science, have clarified the matter for us. God in His original form is not merely the creator, maintainer and destroyer, or the punisher of conditioned souls, but rather the infinitely beautiful Godhead, enjoying in His own right, in His own abode. This is the form of Kṛṣṇa, the same Kṛṣṇa who expands Himself into Viṣṇu forms for the maintenance of our bumbling world.
Śrīla Jīva Gosvāmī mentions that the word śaṅkitaḥ, “having some doubt,” indicates that Mucukunda was thinking, “Is this indeed the Supreme Lord?” He expresses himself frankly in the following verses.
