According to Osho, when you feel useless and do nothing, you align with non-achievement: relax, meditate, and let existence move. Stop trying to be 'useful' - nature's abundance takes care of you, and life unfolds effortlessly. By trusting this spacious uselessness, spontaneity returns, things arrange themselves beautifully, and you are 'spoiled' by existence—that ease and care is the flavor of enlightenment.
If you stop trying to achieve and just relax and meditate, life takes care of you and things sort themselves out.
