According to Osho, people oppose Rajneeshism because it explodes the guilt-and-fear foundations of traditional sado-masochistic religions. His path restores forbidden knowledge and the taste of deathlessness, enabling intelligence, joy, dance, and celebration—thereby ending ecclesiastical control built on sin, ignorance, and dread of death. Such freedom threatens entrenched moralism and power structures, so they condemn what liberates.
Many dislike Rajneeshism because it tells you to be wise and happy instead of guilty and scared, and that threatens the old rule-makers.
