यामा इति समाख्याता देवाः स्वायंभुवेतरे / यमस्य पुत्रा यज्ञस्य तस्माद्यामास्तु ते स्मृताः
yāmā iti samākhyātā devāḥ svāyaṃbhuvetare / yamasya putrā yajñasya tasmādyāmāstu te smṛtāḥ
The gods of that Svāyambhuva Manvantara were renowned as the Yāmās; since they were sons of Yajña, they are remembered by that name.
