Mukti or liberation means to be freed. To be freed from
what? From the body and the world. Liberation takes place when one is freed
from the body and the world.
There is a strong relationship between this body (of ours)
and the world. Our body is made up of precisely those very elements of which
the world is made as well.
There are as many layers or levels of the world such as the
gross layer, the subtle or astral layer, etc as there are in this body.
This body is called pind or microcosm and the world is
called the brahmaand or the macrocosm.
At a given point of time a person remains or lives at the
same level of the world as at the layer of the body in which he is living
currently. Similarly, if one leaves or rises above any layer of the pind or
body, he also transcends the corresponding layer of the brahmaand or world.
Thus, it is known that if one can transcend all the levels
of his/her body, he can transcend all the levels of the world as well.
