अथ यां द्वितीयां जुहुयात्तां जुहुयाद्व्यानाय स्वाहेति व्यानस्तृप्यति ॥ ५.२०.१ ॥
atha yāṃ dvitīyāṃ juhuyāttāṃ juhuyādvyānāya svāheti vyānastṛpyati || 5.20.1 ||
1. When he [the eater] offers the second oblation, he offers it saying, ‘Vyānāya svāhā’ [I offer this as an oblation to vyāna]. With this, vyāna becomes pleased.
Atha, next; yām dvitīyām juhuyāt, when he offers the second [oblation]; tām juhuyāt, he offers that; vyānāya svāhā iti, [with the mantra] ‘Vyānāya svāhā’; vyānaḥ tṛpyati, [then] vyāna is pleased.
Vyāna is the aspect of the vital force responsible for our speech and for feats requiring great effort. It operates on the nerves.
