According to Osho, relaxation and awareness are inseparable—two sides of the same coin. Tension comes from identification with thoughts and fears in the body-mind system. Begin with awareness: witnessing dissolves identification, and relaxation happens naturally, effortlessly. You can also start by relaxing, but forcing it creates new tension; hence awareness-first is the simpler, surer path.
Gently watch what’s happening inside without trying to change it, and your whole body-mind relaxes on its own—forcing relaxation just makes you tighter.
