भूतानां छिद्रदातृत्वं बहिरन्तरमेव च ।
प्राणेन्द्रियात्मधिष्ण्यत्वं नभसो वृत्तिलक्षणम् ॥ ३४ ॥

bahir antaram eva ca
prāṇendriyātma-dhiṣṇyatvaṁ
nabhaso vṛtti-lakṣaṇam
The activities and characteristics of the ethereal element can be observed as the accommodation of room for the external and internal existences of all living entities, namely the field of activities of the vital air, the senses and the mind.
