According to Osho, meditation—especially methods that build intense 'doing' before letting go—helps most people naturally fall into non-doing, producing immediate relaxation, greater depth, and ease. By intentionally creating and then dropping tension, you learn to release mental 'madness' at will; the ensuing stillness arises effortlessly and is usually deeper and more reliable.
Tense up fully, then relax—your mind and body quiet down on their own, and the calm goes deeper.
