dhyāyennṛsiṃhaṃ taruṇārkanetraṃ sidāmbujātaṃ jvalitāgnivatkram /
anādimadhyāntamaja purāṇaṃ parāpareśaṃ jagatāṃ nidhānam //

One should meditate upon the man-lion whose eyes are the newly risen sun, whose lotus face is white, whose mouth is blazing fire, / without beginning, middle, or end, unborn, ancient, ruler of the higher and lower, receptacle of the worlds.
