Will meditation
help an insane person, for example a schizophrenic?
I am afraid
that there are particular kinds of mental disease like schizophrenia,
which are incompatible with meditation of any kind. This group
of people have an imbalance of neuro-chemicals in their brain.
Consequently, they cannot learn from a meditation teacher because
they cannot distinguish genuine instructions from auditory hallucinations.
For this group of people, it is more beneficial for them to use
their time doing good works in society, practising charity and
following the moral precepts. They will always need support, love
and understanding from healthy people as well.
