According to Osho, meditation flowers when you stop clinging to life and allow a deeper 'death' - the dissolution of mind and ego. Ordinary death only changes bodies; true samadhi is the final death where inner and outer merge. Facing death fearlessly, especially in a master's presence, invites this inner funeral: surrender relaxes the mind, ends the wheel of becoming, and opens a boundless, silent awareness.
If you stop being scared of dying, you can let go of the small "me," and your mind becomes calm and open like a big sky.
