The pleasure and suffering are part of the duality. The duality is mere illusion form ultimate standpoint. If one tries to search the source of the mind than it
leads him towards the soul. The soul is the innermost self and the source from
mind arises and subsides as the universe.
Siddhartha the prince with all his comforts of luxuries,
when he saw the suffering he renounced all the pleasures of life and try to
seek the truth of life. When he became aware of the true self, he became aware
of the fact the life is nothingness. That is everything was created out of nothingness
or formless consciousness and everything is nothingness or formless
consciousness.
Modern man is pleasure hunter, and wants only pleasure of
life not pain. Thus everyone is involved in hunting the never ending pleasure,
and they try various methods, which suits to their own mindset, to get that
pleasure that does not pass away.
When one who is able to think, very deeply, will find the
fact that, the pleasure and pain are created out same substance. And the nature
of the substance is formless. The formless substance itself is the true self.
The true self is the source of the experience of diversity (mind or universe or
waking). The whole experience of diversity (I) is erupted out from this
formless source.
Since man thinks he is an individual separate from the
world and limits, the mind (I) to the physical entity, he remains in ignorance,
and experiences the duality as reality. Thus he accepts the suffering as part
of his life.
The pleasure and pain are impermanent within the experience
of impermanence (mind or universe or waking). The mind (I) which appeared on
its own also disappears on its own. The one, which knows the mind is created
out of nothingness or formless consciousness and that nothingness or formless consciousness is the inner most
self and it is everything, is free from the ignorance,
which is the cause of the experiencing pain and pleasure as reality and it
itself is uncaused.
