Sorry, this is interesting, but no prize. Training the mind and even reaching some sort of epiphany of cosmic or spiritual enlightenment will not eliminate the majority of the suffering of this world. Physical, mental and emotional suffering are inextricably connected. The problem is intractable because the brain is intentionally designed by evolution for the conscious self to suffer, to feel pain in response to damage, and is "wired" so that pain = suffering as a biological fact. Humans can't transcend their inherent biological nature as animals whose physical bodies break down or are damaged, generating suffering in the process.
