Is the soul really immortal?
Hindu religious texts assert that the soul is part of the Supreme Spirit. Therefore, like God, the soul too is eternal. However, in this world the soul has an entity. When the soul enters a body it is given the name of the person. The soul has no colour, form or sex.
In the Rig-Veda, 1/164/38, it is said:
The soul is immortal. The physical body is destructible. The soul controls all the functions in the body. The body functions as long as the soul resides within it. The most learned people do not understand the mysteries of the soul. The principal aim of life should be to understand it to the best of one's ability.
In the Brihadranyak Upanishad, 8/7/1, it is said that the soul never sins. It never grows old. It is free from death and sorrow. It is never hungry or thirsty. It has no desires, but we should desire it. It does not dream of anything, but we should dream about it. It is an entity that we must try to understand better.
In the Bhagavad Gita, 2/20, there is a reference to the immortality of the soul:
The soul was never born, nor does it die. It will not emerge again. It is unborn, eternal, everlasting and without age. Even when the body is destroyed, the soul remains untouched.
In the Bhagavad Gita, 2/22, there is further reference to the soul:
Just as a man discards his old clothes and takes on new ones, in the same way the soul discards the old body and enters a new one.
It is also said that weapons cannot cut a soul. Nor can fire burn it. Water cannot wet it, nor can air dry it. The soul is eternal, omnipresent, immovable, constant and everlasting.
It is believed that it takes i3 days for the soul to avoid going into an inauspicious form of a ghost or spirit. It is therefore customary to offer prayers and give charity to seek peace for the soul. It is only after 13 days that the soul moves on to meet the forefathers.
