I am not very adept at the sciences.
As you know much that occurs begins in the mind (or the brain which witholds tmind.) The goal is to have the nerve impulses moving in an orderly fashion so, the pattern is like high speed electricity, smooth flowing.

In the brain one nerve sends messages to the next nerve, second nerve catches charges through dendrites. Many things can go wrong:
1. The first nerve can send charges too quickly
2. The first nerve can send charges too slowly
3. The second nerve can miss the charges

There are physical aspects to enlightenment. When people pray or meditate on a constant basis, they are aligning the nerves so that functioning of the nerves and the activity between them are aligned.

How do you feel after a meditation you use all the time or a prayer you say so much that you don't even have to think about it. What do you think occurs during that meditation or prayer? Remember enlightenment occurs on more than one level of the human being.

What other sciences can explain the physical aspect of enlightenment?
