Despite dwelling in a material body of four elements, your nature is basically pure. It can’t be corrupted. Youre real body has no sensation, no hunger or thirst, no warmth or cold, no sickness, no love or attachment, no pleasure or pain, no good or bad, no shortness or length, no weakness or strength. Actually, there’s nothing here. It’s only because you cling to this material body that things like hunger and thirst, warmth and cold, and sickness appear.
Once you stop clinging and let things be, you’ll be free, even of birth and death.
Bodhidarma, Bloodstream Sermon.
