Soul. Aatmaa is
pure and never dies.
In Naarad Puraan, p
433, four types of Aatmaa are mentioned -
(1) Aatmaa - Soul,
(2) Antar-Aatmaa - Inner Conscious,
(3) Param-Aatmaa - Ultimate Soul or Bhagavaan, and
Aatmaa has 13
It cannot be burnt, It cannot be wet, It cannot be dried, It cannot be
devoured by any weapon,
It is not the subject of Indriyaan, It has no Vikaar (it is unchangeable),
It is immortal,
2/23-25, also Bhagavaan Krishn says to Arjun, telling the
characteristics of the soul -
"Neither weapons can devoured this soul, nor fire can burn it, nor water
can wet it, nor air can dry it. This soul is un-pierceable, un-burnable,
un-dryable. It is undoubtedly omnipresent, immovable and immortal. This
soul is not the subject of Indriyaan, not thinkable by mind, and is
unchangeable; that is why, Hey Arjun, considering the soul like this, you
should not lament for it."
Aatmaa :- A
reflection of Poorn Brahm inside us and every earthly and divine body.
Pretaatmaa :- A body (those are not of this plane) that is given to us
after our death due to our Karm. It is also called "Yaatana Shareer". A
body that is given to us for tormenting in hell and on the earth.
Dhundhukaaree in Bhaagvat Puraan is an example of this. There are many
such Yaatanaa or Niyantrit Shareer, like Pishaach, Raakshas, Asur, Brahm
Raakshas (Pret of a Braahman), Dankinee and many others.
Furthermore - Pretaatmaa is not the soul of the dead, it is the another
body for the dead that is not earthly. There can be other good bodies too,
like Dev Yoni, Pitri Yoni, Gandharv Yoni, Yaksh Yoni, Vidhyaadhar Yoni and
many others. You can call them good "Ghosts" but the ghost word is not
them. Aatmaa also resides in these bodies but they are not Aatmaa. Aatmaa
is independent of all. The Shuddh or pure reflection of God is Aatmaa,
irrespective of any earthly and divine body. Even Devtaa are not Aatmaa -
they are in Dev Yoni.
