"A Person may become convinced that everything is an illusion, unreal, and may believe he can do anything. But this is a big mistake. As long as we have a body we must respect all of it's limits and needs. If we touch fire with our finger, we immediately feel it burn and pull it back.
This means we have not realized the condition in which there is no I, in which the limits of the physical body no longer remain."
- Namkhai Norbu Rinpoche
