2.4.2

yasya priyo bubhūṣed yasyai vā yeṣāṃ vā yāsāṃ vaiteṣām evaikasmin parvaṇy agnim upasamādhāyaitayaivāvṛtaitā ājyāhutīr juhoti /

If one should desire to become beloved of a man, or of a woman, or of men, or of women—at one of these same [aforementioned] points of time, having built up a fire, he in the same manner offers these oblations of melted butter:— 'Your Speech I sacrifice in me, you so-and-so! Hail! Your Breath I sacrifice in me, you so-and-so! Hail! Your Eye I sacrifice in me, you so-and-so! Hail! Your Ear I sacrifice in me, you so-and-so! Hail! Your Mind I sacrifice in me, you so-and-so! Hail! Your Intelligence I sacrifice in me, you so-and-so! Hail!' Then, having sniffed the smell of the smoke, having rubbed his limbs over with a smearing of the melted butter, silently he should go forth and desire to approach and touch, or he may simply stand and converse from windward. He becomes beloved indeed. They long for him indeed.
