Bhagavad Gita 2.16

नासतो विद्यते भावो नाभावो विद्यते सत: ।
उभयोरपि दृष्टोऽन्तस्त्वनयोस्तत्त्वदर्शिभि:  ॥

nāsato vidyate bhāvo nābhāvo vidyate sata:
ubhayor-api dṛṣṭo’ntas-tvanayos-tattva-darśibhi: – 2.16

The ‘unreal’ has no expression. The ‘real’ will never cease to be. By experts in the knowledge of Truth, the difference between the two (the Real and the Unreal) has clearly been ascertained.
