People often get hung up on the physical body, believing it is the end all and be all of existence. But individuality is far more.
You have a spiritual individuality that lives forever. It never dies, expires, ends, or gets sick. It is made in the likeness of God and is above anything the material senses can comprehend.
The cool part is, that the more you identify with your spiritual individuality, the better things go physically, for in truth, you have only one individuality, your spiritual existence with God.
What is called a physical body is a finite view of man held in mortal mind. It’s not another you, apart from your spiritual individuality. It’s a temporal concept. It’s like believing the Statue of Liberty embodies liberty. It does not. It’s a symbol, not the substance of liberty. Liberty would not cease to exist if the Statue of Liberty ceased to exist. Likewise, physicality is never a threat to your spiritual individuality. Your individuality in Spirit is forever safe.
As Jesus Christ proved, the more we understand spirituality, the more dominion and authority we can exercise over physicality, to straighten it out and bring it into line with spiritual truth.
Physicality is a false concept of man begging to be rectified with a right spiritual understanding of man.
Focus on spiritual individuality, rather than physicality, and you’ll find more dominion over the body.
“Rightly understood, instead of possessing a sentient material form, man has a sensationless body; and God, the Soul of man and of all existence, being perpetual in His own individuality, harmony, and immortality, imparts and perpetuates these qualities in man, — through Mind, not matter” (Science and Health with Key to the Scriptures, Mary Baker Eddy, p. 280).
