"The Vedas inform us that He alone became many, and when He so desires He glances over material nature. Before He glanced over material nature there was no material cosmic creation. Therefore, His glance is not material. Material mind or senses were unborn when the Lord glanced over material nature. Thus evidence in the Vedas proves that beyond a doubt the Lord has transcendental eyes and a transcendental mind. They are not material. His impersonality therefore is a negation of His materiality, but not a denial of His transcendental personality.
"Brahman ultimately refers to the Personality of Godhead. Impersonal Brahman realization is just the negative conception of the mundane creations. Paramātmā is the localized aspect of Brahman within all kinds of material bodies. Ultimately the Supreme Brahman realization is the realization of the Personality of Godhead. Lord Śrī Kṛṣṇa is that Supreme Personality of Godhead according to all evidence of the revealed scriptures. He is the ultimate source of viṣṇu-tattvas.
