According to Osho, your body’s lack of grace simply mirrors your heart’s current state. The body obeys the heart; stiffness shows hurt pride, unconscious expectations, and jealousy from feeling replaced. Love tinged with demand becomes stone-like. Drop expectations, let love be unconditional, accept that life moves on, and your body will naturally soften and respond to the energy being shared.
Your stiff body is your hurt feelings showing; if you stop expecting special treatment and love without demands, your body will relax.
