What do you mean when you say, 'Be yourself'?

According to Osho, “Be yourself” does not mean strengthen the ego; it means drop it. The word self has two meanings: the false self (ego/personality) and the real Self (soul/consciousness). To know yourself, first be yourself—rest as egoless presence, a simple am‑ness or isness without boundaries. In meditation, when “I” disappears, your true being flowers.
