I will start with a true story. Somewhere in US a group of scientists decided to create in laboratory the see water i.e. the true water which exist in the see. After some studies they succeeded. To control the quality of water they have introduced a small fish. Surprisingly, the fish died after few seconds. This happened in spite of the composition which reproduced exactly the composition of natural see water. Millions of molecules from the lab water were the same as in the natural see water. Still the life of fish stopped while in the natural see water was possible. In my opinion the missing was the touch of Divinity. (The lab water was a human creation)
So we are. We, the disable people are form by millions and millions of molecules and atoms. Unfortunatedly for some of us some molecules are missing. But all of us, as for normal people have the touch of Divinity. That means that all of us have the same quality as the normal people-the essential part of.
