Srimad Bhagavatam — Shashtha Skandha, Shloka 52
Viśvarūpa’s Death, Vṛtrāsura’s Manifestation, and the Devas’ Surrender to Nārāyaṇa
स वा अधिगतो दध्यङ्ङश्विभ्यां ब्रह्म निष्कलम् । यद्वा अश्वशिरो नाम तयोरमरतां व्यधात् ॥ ५२ ॥
sa vā adhigato dadhyaṅṅ aśvibhyāṁ brahma niṣkalam yad vā aśvaśiro nāma tayor amaratāṁ vyadhāt
圣者达提央叉（达提奇）亲自领悟了无杂的梵智之学，并将其传授给阿湿毗尼双子。据说他借马头传授咒语，因此这些咒语称为“阿湿瓦希罗”(Aśvaśira)。阿湿毗尼双子得此灵性真言后，成为“现生解脱者”(jīvan-mukta)，即于此生亦得解脱。
The following story is narrated by many ācāryas in their commentaries:
FAQs
The Aśvinī-kumāras are the twin divine physicians among the devas; this verse states that Dadhyaṅg transmitted to them flawless brahma-vidyā (spiritual knowledge), and is also remembered as granting them immortality under the name Aśvaśirā.
In the narrative surrounding the devas’ crisis and the events leading to Vṛtrāsura’s appearance, Śukadeva highlights prior episodes of sacred knowledge and divine arrangements—such as Dadhyaṅg’s gift to the Aśvins—to show how higher wisdom and divine boons shape outcomes beyond mere power struggles.
Seek “niṣkala” knowledge—pure, undivided spiritual understanding—through authentic transmission and humility, and value wisdom over temporary gains, since true upliftment comes from realized knowledge and its proper sharing.
