Since the mind is responsible for everything happens in our life either
physical or Psychological.
The Supreme Spirit (Paramatma) has assigned some duties to be performed
to its particle, i.e. Soul (Jeevatma) while on the body of a human.
But once the soul enters into the human body with mind and senses, and
the infant grows up, as mentioned in the previous chapter, its mind
involves many good and evil actions, desires, etc. and forgets about the
obligatory duty which has to be performed while on the body.
Soul and its true nature are simply and beautifully explained in this
book.
