The purpose of a soul being placed inside each and every one of us is to discover the Oneness which comprises Universal Energy. We discover our Energy by maintaining a symmetry with our soul and our body.
Not only that, but you can achieve serenity by striving to ensure your soul remains dominant over your body. Your body can give in to your soul, but your soul cannot be overpowered by your body. That’s because your soul is inherently part of The Omnipotent One, which is everlasting. Your body only has a finite life span.
