According to Osho, what matters in meditation is totality, safety, and freedom from distraction—not rules about accessories. Because the process may include swaying, dancing, or even falling, arrange space and drop anything that could hinder or hurt you. If glasses feel risky or distracting, take them off; if they support comfortable awareness (e.g., when looking toward the master), keep them on. Choose what best serves total involvement.
If your glasses might get in the way or make movement unsafe, take them off; otherwise, keep them if they help you stay present.
