RV 10.12.6
दुर्मन्त्व् अत्रामृतस्य नाम सलक्ष्मा यद् विषुरूपा भवाति । यमस्य यो मनवते सुमन्त्व् अग्ने तम् ऋष्व पाह्य् अप्रयुच्छन् ॥
durmantv atrāmṛtasya nāma salakṣmā yad viṣurūpā bhavāti | yamasya yo manavate sumantv agne tam ṛṣva pāhy aprayucchan ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
'Tis hard to understand the Immortal's nature, where she who is akin becomes a stranger. Guard ceaselessly, great Agni, him who ponders Yama's name, easy to be comprehended.
Translated by Ralph T. H. Griffith (1896)
