According to Osho, the master-disciple experience is a paradoxical, non-relational oneness: in two bodies one heart throbs. It exists to dissolve duality - the disciple's ego and even attachment to the master. The master is a compassionate stepping stone, not a destination. When the final clinging is 'killed,' master and disciple vanish together, leaving utter inner silence and direct realization of the infinite.
A true master joins with you to help you forget your small self, and when you're ready, asks you to let even them go so you can find the quiet truth inside.
