Chandogya Upanishad 5.22

atha yāṃ caturthīṃ juhuyāt tāṃ juhuyāt samānāya svāheti samānas tṛpyati

'And he who offers the fourth oblation, should offer it to Samâna (on-breathing), saying Svâhâ. Then Samâna is satisfied,

samāne tṛpyati manas tṛpyati manasi tṛpyati parjanyas tṛpyati parjanye tṛpyati vidyut tṛpyati vidyuti tṛpyantyāṃ yat kiṃca vidyuc ca parjanyaś cādhitiṣṭhatas tat tṛpyati tasyānu tṛptiṃ tṛpyati prajayā paśubhir annādyena tejasā brahmavarcaseneti

'If Samâna is satisfied, the mind is satisfied, if the mind is satisfied, Parganya (god of rain) is satisfied, if Parganya is satisfied, lightning is satisfied, if lightning is satisfied, whatever is under Parganya and under lightning is satisfied. And through their satisfaction he (the sacrificer or eater) himself is satisfied with offspring, cattle, health, brightness, and Vedic splendour.
