According to Osho, being unique is your inherent, incomparable nature—there is no other you, so comparison drops and you simply are. Being special is a comparative claim of superiority or inferiority; it breeds ego, ambition, jealousy, and violence, creating misery. Uniqueness is religious, nonviolent presence; specialness is political struggle. Live an uncompared life—neti-neti, just yourself—and inner freedom, peace, and purity arise.
Unique means being yourself without comparing; special means trying to be better than others, which causes trouble.
