According to Osho, the pain of longing when you feel physically distant is not about space but about separation from your own true self; the master mirrors your future being, so intimacy coexists with distance until love becomes oneness. By dropping conditions, expectations, and the ego—moving from student to disciple to devotee—you become a pure presence, and the illusion of distance dissolves.
The hurt of missing someone far away is really you missing your own deepest self; let go and be simply present, and the gap vanishes.
