Atharva Veda
For virile power
ā vṛṣāyasva śvasihi vardhasva prathayasva ca yathāṅgaṃ vardhatāṃ śepas tena yoṣitam ij jahi
For virile power
Play thou the bull, blow, increase and spread; let thy member increase limb by limb; with it smite the woman.
yena kṛśaṃ vājayanti yena hinvanty āturam tenāsya brahmaṇaspate dhanur ivā tānayā pasaḥ
Wherewith they invigorate one who is lean, wherewith they incite (hi) one who is ill—with that, O Brahmaṇaspati, make thou his member taut like a bow.
āhaṃ tanomi te paso adhi jyām iva dhanvani kramasvarśa iva rohitam anavaglāyatā sadā
I make thy member taut, like a bowstring on a bow; mount, as it were a stag a doe, unrelaxingly always.
