brahma satyaṁ jagan mithyā | jīvo brahmaiva nāparaḥ || anena vedyaṁ sacchāstram | iti vedānta-ḍiṇḍimaḥ || 

MANTRA MEANING:

Brahman alone is real. The individual self is none other than Brahman. This is the essential truth to be known from the teachings — such is the resounding proclamation of Vedānta. — Brahma-jñānāvalī-mālā 20, traditionally attributed to Ādi Śaṅkarācārya
