RV 7.3.2
प्रोथद् अश्वो न यवसे ऽविष्यन् यदा महः संवरणाद् व्य् अस्थात् । आद् अस्य वातो अनु वाति शोचिर् अध स्म ते व्रजनं कृष्णम् अस्ति ॥
prothad aśvo na yavase 'viṣyan yadā mahaḥ saṃvaraṇād vy asthāt | ād asya vāto anu vāti śocir adha sma te vrajanaṃ kṛṣṇam asti ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Like a steed neighing eager for the pasture, when he hath stepped forth from the great enclosure: Then the wind following blows upon his splendour, and, straight, the path is black which thou hast travelled.
Translated by Ralph T. H. Griffith (1896)
