According to Osho, Zen is Buddha’s wordless transmission to Mahakashyapa—the inner science of no-mind. India, bound to scholarship and priestly authority, couldn’t receive it, so Bodhidharma carried the living flame to China and Japan where it flowered. Its return to India signifies readiness to drop intellectualism for meditation, restoring the original experiential essence at its source.
Buddha gave Zen beyond words; India wasn’t ready, so it grew in China/Japan, and its return means India may finally practice silence and meditation instead of arguing ideas.
