Translation:

“My Lord Viṣṇu, full in six opulences, You are the best of all enjoyers and the most powerful. O husband of mother Lakṣmī, I offer my respectful obeisances unto You, who are accompanied by many associates, such as Viśvaksena. I offer all the paraphernalia for worshiping You.” One should chant this mantra every day with great attention while worshiping Lord Viṣṇu with all paraphernalia, such as water for washing His feet, hands and mouth and water for His bath. One must offer Him various presentations for His worship, such as garments, a sacred thread, ornaments, scents, flowers, incense and lamps.

Purport:

This mantra is very important. Anyone engaged in Deity worship should chant this mantra, as quoted above, beginning with oṁ namo bhagavate mahā-puruṣāya.
