According to Osho, not at all: the idea that you become what you ceaselessly strive for and imagine is self-hypnosis, not awakening. There is nothing to become; your essence already is, like the Kohinoor beneath mud. Drop imaginative overlays, refine awareness, and cut away the nonessential; then reality reveals itself. Imagination paints spectacles; removing them restores clear seeing—value grows as egoic weight falls.
No—pretending very hard won’t make you that; you’re already a jewel, just clean the dust from your eyes instead of daydreaming.
