According to Osho, transcendence doesn’t require a healthy body; the body is inherently mortal and unreliable. Let mortality spur your search. Use illness and despondency as fuel: practice simple awareness of breath: sitting, standing, walking, or lying down. Continuous Vipassana disidentifies you from body and mind, revealing the deathless within. Even in a hospital bed, just watch the breath; nothing else is needed.
Even if you feel sick or sad, gently notice each breath all the time, and you’ll find the part of you that doesn’t get sick or die.
