Sanskrit:
अन्वजानंस्तत: सर्वे ग्रहं सोमस्य चाश्विनो: ।भिषजाविति यत् पूर्वं सोमाहुत्या बहिष्कृतौ ॥ २६ ॥
ITRANS:
anvajānaṁs tataḥ sarvegrahaṁ somasya cāśvinoḥbhiṣajāv iti yat pūrvaṁsomāhutyā bahiṣ-kṛtau
Translation:
Although the Aśvinī-kumāras were only physicians and were therefore excluded from drinking soma-rasa in sacrifices, the demigods agreed to allow them henceforward to drink it.
