नासतो विद्यते भावो नाभावो विद्यते सतः। उभयोरपि दृष्टोऽन्तस्त्वनयोस्तत्त्वदर्शिभिः
nāsato vidyate bhāvo nābhāvo vidyate sataḥ ubhayorapi dṛiṣhṭo ’nta stvanayos tattva-darśhibhiḥ
That which is not shall never be; that which is shall never cease to be. These truths are self-evident to the wise.
Translated by Shri Purohit Swami
The unreal has no being; there is no non-being of the real; the truth about both has been seen by the knowers of the truth (or the seers of the essence).
Translated by Swami Sivananda
