Lord Śiva is rarely seen by common men, and similarly a person who is fully surrendered unto Vāsudeva, Kṛṣṇa, is also very rarely seen because a person who is fully surrendered unto the Supreme Lord is very rare (sa mahātmā sudurlabhaḥ). Consequently Lord Śiva came especially to see the Pracetās because they were fully surrendered unto the Supreme Personality of Godhead, Vāsudeva. Vāsudeva is also mentioned in the beginning of Śrīmad-Bhāgavatam in the mantra, oṁ namo bhagavate vāsudevāya. Since Vāsudeva is the ultimate truth, Lord Śiva openly proclaims that one who is a devotee of Lord Vāsudeva, who is surrendered to Lord Kṛṣṇa, is actually very dear to him. Lord Vāsudeva, Kṛṣṇa, is worshipable not only by ordinary living entities but by demigods like Lord Śiva, Lord Brahmā and others. Yaṁ brahmā-varuṇendra-rudra-marutaḥ stuvanti divyaiḥ stavaiḥ (SB 12.13.1). Kṛṣṇa is worshiped by Lord Brahmā, Lord Śiva, Varuṇa, Indra, Candra and all other demigods.
