.............now did you point to your head, your arm or leg or did you point to your heart? When we talk about the 'self' are we talking about our body, our brain or something within? The majority of you would have pointed to the heart. Now doesn't that tell you something? It is not surprising that the heart is the resting place for the soul and it is the soul that pervades the whole body with life essence.
Compare a living being with a dead body, what is the difference? We say the person has 'gone' yet the body remains, so it must be something within that has gone. It is the soul within that is our real identity and gives the life symptoms to the body. After giving up one type of body, the soul enters another type of body, similar to taking off and putting on new clothes.
We are not the body but the soul within the body.
This is confirmed in the Bhagavad Gita by the supreme personality of Godhead, Lord Krishna himself.
