According to Osho, concentration is the mind’s forced narrowing that generates energy and psychic powers but tightens the ego, creates inner tension, and blocks the ultimate relaxation of meditation; such rigidity can unbalance the mind. True meditation is effortless, empty looking—relaxed, unblinking awareness—where boundaries dissolve, bliss arises, and sanity flowers.
Don’t strain to focus; just relax and look openly, and your mind stays healthy and peaceful.
