Lord Vāsudeva, or Śrī Kṛṣṇa, the son of Vasudeva, is the Supreme Personality of Godhead. He is manifest within the hearts of yogīs in His Paramātmā feature, and He is worshiped as impersonal Brahman by jñānīs. The Paramātmā feature is described in the śāstras as having four hands, holding disc, conchshell, lotus flower and club. As confirmed in the Śrīmad-Bhāgavatam (2.2.8):
prādeśa-mātraṁ puruṣaṁ vasantam
gadā-dharaṁ dhāraṇayā smaranti
Paramātmā is situated in the hearts of all living beings. He has four hands, which hold four symbolic weapons. All devotees who think of the Paramātmā within the heart worship the Supreme Personality of Godhead as the temple Deity. They also understand the impersonal features of the Lord and His bodily rays, the Brahman effulgence.
