According to Osho, Buddha says 'be a light unto yourself' because true guidance cannot be borrowed from scriptures, traditions, or teachers; they are only signposts. Only your own alertness, meditation, and direct experience can dispel inner darkness. Trust your witnessing consciousness, keep inquiring, and let understanding arise from within rather than from imitation or belief.
Don’t depend on others to tell you the truth; look inside with clear awareness and let your own clarity guide you.
