According to Osho, inner strength arises when repression ends—especially around sex—and one’s natural energies are accepted as normal. Granting freedom in love dissolves shyness and indecision; the inner fight stops, and a unified, “one solid individual” emerges. From this wholeness comes decisiveness, confidence, and vitality; you don’t need training, only permission to be natural, playful, and unafraid.
Stop fighting your natural feelings (especially about love and sexuality), accept them kindly, and your confidence and clear decisions will grow on their own.
