The Personality of Godhead is pure, being free from all contaminations of material tinges. He is the Absolute Truth and the embodiment of full and perfect knowledge. He is all-pervading, without beginning or end, and without rival. O Narada, O great sage, the great thinkers can know Him when completely freed from all material hankerings and when sheltered under undisturbed conditions of the senses. Otherwise, by untenable arguments, all is distorted, and the Lord disappears from our sight. (SB 2.6.40/41)
