Time 2

In a mind-based world view even the body is upheld by mind. Not directly, but with the help of an intricate system of stronger and stronger structures.
At death, when mind leaves the body, the decay starts almost instantly.
During life, the support of mind for the body can be more or less efficient. When the support is bad, the body ceases to function.
Normally the mind renovates the body every night when we sleep. It takes place during the first part of the sleep, in the dreamless, dark period.
So if we want to live long, we have to have a vital mind.
Mind can not give the body eternal life, but mind can prepare us for an existence without a body.
If we have a body-based world view we are at risk of focusing too much on material issues.
