Our past, present and future - all is stored in the Antahkarna, which is the connection with the divine seen in the form of a tube of light above the head. When people who have had near death experiences are asked to recount their experience, they generally describe going through a tunnel filled with bright light. While a normal being traverses this tube only when the soul enters and exits a body i.e. Birth & Death; yogis can experience it at will in the deep state of dhyan. They can transcend time to co-exist in the past, present and future by accessing the higher states of consciousness. There are four states of the mind – conscious, subconscious, unconscious and super-conscious (known as turaiya stage). Past life Regression is the function of this fourth stage.

Revelations of Past life are meant to aid the cause of Creation. We are all divine beings going through a human experience. In this human journey we have forgotten our true purpose. The fads and therapies that are picked up today in the name of Past life Regression are nothing but a play of the subconscious working on the same principle as dreams. The subconscious mind keeps on storing images and information one intercepts through day. In state of hypnosis one is made to visit all those stored things just put together, misinterpreted as a Past life. While this technique has proved beneficial remedy for psychological disorders but it can no way be called Past life Regression.

A visit to the Past life helps revive parts of the memory, which lie dormant within us. However to access ones past lives, the Antahkarna must be awakened. This calls for certain purifications at the physical as well as etheric levels by way of Yogic practices.

One of the most effective purification techniques prescribed in the Sanatan Kriya is to pay-off ones dues, Charity and non-hoarding. St Francis rightly said "it is in giving that we receive; 
it is in pardoning that we are pardoned; 
and it is in dying that we are born to eternal life."
