Bhagavad Gita 2.16

नासतो विद्यते भावो नाभावो विद्यते सतः।उभयोरपि दृष्टोऽन्तस्त्वनयोस्तत्त्वदर्शिभिः ॥२.१६॥

nāsato vidyate bhāvo nābhāvo vidyate sataḥubhayorapi dṛṣṭo’ntastvanayostattvadarśibhiḥ

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).
