द्वाविमौ पुरुषौ लोके क्षरश्चाक्षर एव च।क्षरः सर्वाणि भूतानि कूटस्थोऽक्षर उच्यते।।15.16।।
dvāv imau puruṣhau loke kṣharaśh chākṣhara eva cha kṣharaḥ sarvāṇi bhūtāni kūṭa-stho ’kṣhara uchyate
Two Purushas there are in this world: the perishable and the imperishable. All beings are perishable, and the Kutastha—the unchanging—is called the imperishable.
