Rāmānujaon Brahma Sūtra 2.3.8
Viśiṣṭādvaita Vedānta
Sūtra
एतेन मातरिश्वा व्याख्यातः
etena mātariśvā vyākhyātaḥ
Sūtra translation
Hereby air is explained.
The same argumentation explains the origination of air also. That a special Sûtra is devoted to the origination of air—instead of disposing in one Sûtra of Ether and air—is for the sake of Sûtra 10, which states that 'hence (i.e. from air) there originated fire.'
