53.2

yadā parjanyo bhūtvābhivarṣasi tvamatha tadānnaṃ prāpyemāḥ prajāḥ prāṇate prāṇaceṣṭāṃ kurvantītyarthaḥ /
athavā prāṇa te tavemāḥ prajāḥ svātmabhūtāstvadannasaṃvardhitāstvadabhivarṣaṇadarśanamātreṇa cānandarūpāḥ sukhaṃ prāptā iva satyaḥ tiṣṭhanti kāmāyecchāto 'nna bhaviṣyatītyevamabhiprāyaḥ //10//

Yadā, when; tvam, you; abhivarṣasi, pour down, by becoming rain cloud; atha, then; getting food; imāḥ prajāḥ, all these creatures; prāṇate, live, that is to say, resort to activities characteristic of vitality. Or (reading prāṇa te in place of prāṇate): prāṇa, O Prāṇa; imāḥ prajāḥ te, these creatures of yours—which are one with you and which are nourished by your food; at the very sight of the rain you pour down; tiṣṭhanti, continue to be; ānandarūpāḥ, like people possessed of happiness; their idea being this: "Annam bhaviṣyati, food will be produced; kāmāya, to our hearts' content."
