There are many standards of perfection. The highest material perfections, obtained by perfect yogīs, are listed as eight: to become the smallest of the small, to become the greatest of the great, etc. All of these material perfections, as well as all spiritual perfections, can be found fully in Kṛṣṇa's personality. 56. Kṛṣṇa's Inconceivable Potencies
Kṛṣṇa is present everywhere, not only within the universe, not only within the heart of all living entities, but also within every atom. In the prayers of Queen Kuntī we find mention of this inconceivable potency of Kṛṣṇa. While Kṛṣṇa was talking with Kuntī, He simultaneously entered the womb of Uttarā, who was in danger due to the atomic weapon of Aśvatthāmā. Kṛṣṇa can illusion even Lord Brahmā and Lord Śiva, and He can protect all surrendered devotees from the reaction of sinful activities. These are some of the examples of His inconceivable potencies.
Śrīla Rūpa Gosvāmī therefore offers his obeisances unto Kṛṣṇa by saying, "Kṛṣṇa, who is present as a human being, has as His mere shadow the whole material nature. He has expanded Himself into so many cows, calves and cowherd boys, and He has again manifested Himself in all of them as the four-handed Nārāyaṇa. He has taught millions of Brahmās self realization, and thus He is worshipable not only by the heads of all universes, but by everyone else also. Therefore let me always accept Him as the Supreme Personality of Godhead."
When Indra was defeated by Kṛṣṇa in the matter of taking the pārijāta plant from heaven, Nārada met Indra and criticized him: "O Indra, great King of heaven, Kṛṣṇa has already defeated Lord Brahmā and Lord Śiva. So what can be said of an insignificant demigod like you?" Nārada Muni, of course, was criticizing Indra jokingly, and Indra enjoyed it. In Nārada's statement it is confirmed that Kṛṣṇa was able to illusion even Lord Brahmā and Lord Śiva as well as Indra. So there is no question of Kṛṣṇa's power to do the same to lesser living entities.
