Satī at Dakṣa’s Sacrifice: Condemnation of Blasphemy and Voluntary Departure by Yoga-Fire
अध्वर्युणा हूयमाने देवा उत्पेतुरोजसा । ऋभवो नाम तपसा सोमं प्राप्ता: सहस्रश: ॥ ३३ ॥
adhvaryuṇā hūyamāne devā utpetur ojasā ṛbhavo nāma tapasā somaṁ prāptāḥ sahasraśaḥ
当祭司（adhvaryu）向祭火献供之时，诸天以威力立刻显现。名为“利布”（Ṛbhu）的天众因苦行得月神苏摩之力，成千上万地出现。
It is stated here that many thousands of demigods named Ṛbhus became manifested because of the oblations offered in the fire and the chanting of the hymns from the Yajur Veda. Brāhmaṇas like Bhṛgu Muni were so powerful that they could create such powerful demigods simply by chanting the Vedic mantras. Vedic mantras are still available, but the chanters are not. By chanting Vedic mantras or chanting the Gāyatrī or ṛg-mantra one can attain the results one desires. In the present Age of Kali it is recommended by Lord Caitanya that simply by chanting Hare Kṛṣṇa one can attain all perfection.
