āpaḥ

नैनं छिन्दन्ति शस्त्राणि नैनं दहति पावकः

āpaḥ — water

Weapons do not cut it, fire does not burn it, water does not wet it, wind does not dry it.

आपूर्यमाणमचलप्रतिष्ठं समुद्रमापः प्रविशन्ति यद्वत्

āpūryamāṇam — filled from all sides

As rivers enter the ocean, which is filled and yet unmoved at its foundation, so all desires enter the one who is at peace.

भूमिरापोऽनलो वायुः खं मनो बुद्धिरेव च

āpaḥ — water

Earth, water, fire, air, space, mind, understanding and the sense of self — these are the eight divisions of my lower nature.
