According to Osho, when fear arises in meditation you touch the mind’s basic fear: death. Look at it directly and recall that death is only an idea borrowed from watching others, while life is your own inner reality. By turning inward and tasting this living presence—like love known from within—the notion of death drops, and fear (and related guilt) dissolves into clarity and peace.
Notice the fear or guilt, remember it’s based on an idea of death, and feel the alive, timeless presence inside—then it fades.
