न तथा विद्यते व्याप्तिर्वह्न्यादेः खनभस्वतोः ।सूक्ष्मत्वादंशकव्याप्तेस्तद्धर्मो नोपलभ्यते ॥ ४०७ ॥
In plain words
Such pervasion by fire and other gross elements does not occur in ether and air; due to extreme subtlety and fractional presence, their specific traits remain imperceptible.
Close to the Sanskrit
The pervasion of fire and others is not thus in ether and wind; because of subtlety and fractional pervasion, its property is not perceived.
