According to Osho, effortless effort means using life’s polarities—intense activity and deep rest—so energy becomes dynamic and self-balancing. In meditation you don’t chase a dead, forced silence; you move totally into action, then totally into letting go, allowing a living silence to arise by itself. This dialectical approach underlies dynamic meditation: catharsis then stillness, effort then surrender, producing a vital, present silence.
Go all-in when active, then completely relax—real silence appears on its own.
