The Prashna Upanishad with Shankara’s Commentary
यदा त्वमभिवर्षस्यथेमाःप्राण ते प्रजाः ।
आनन्दरूपास्तिष्ठन्ति कामायान्नं भविष्यतीति ॥ १० ॥
yadā tvamabhivarṣasyathemāḥprāṇa te prajāḥ |
ānandarūpāstiṣṭhanti kāmāyānnaṃ bhaviṣyatīti || 10 ||
10. When you rain, all round; then Oh Prâna, these, your creatures, sit delighted thinking there will be food at their desire.
Com.—When you in the form of clouds, rain all round; then, having obtained food, these creatures put forth activity. Or, Oh Prâna, these, your creatures, being yourself and nourished by your food, become delighted with the mere sight of the rain you pour, thinking there will be food at their desire.
