Body

How does one engage with the body in the journey to understand the "I" ? In any case the body seems to be the first port of call. It seems to be the first within reach. I now feel the weight of the body. Its salty taste. Right now. Now what? Feel the difference between the "I" and this body? When will I be able to experientially break the knot of the inner imagery of being the body? Permanently? and escape death by dying before hand.
