harir hi nirguṇaḥ sākṣāt puruṣaḥ prakṛteḥ paraḥ sa sarva-dṛg upadraṣṭā taṁ bhajan nirguṇo bhavet

"The Supreme Personality of Godhead, Hari, is always uncontaminated by the modes of material nature, for He is beyond the material manifestation. He is the source of the knowledge of all the demigods, headed by Lord Brahma, and He is the witness of everything. Therefore one who worships the Supreme Lord Visnu also attains freedom from the contamination of material nature." (Bhag. 10.88.5) One can attain freedom from the contamination of material nature by worshiping Visnu, and therefore He is called Sattvatanu, as described above.
