Understanding of the soul To talk about "vibrant" the way you do, is to make the soul material. It's like saying the soul is energy. It's a sign of corruption.
The soul chooses, and only a chosen judgement can identify what emotions are in the soul. That are the rules which logic dictates. To make the soul material, means to make the soul factual. Facts are forced by evidence, not chosen. Which means to throw out chosen judgement based on human emotions, the human spirit, and throw out chosen judgement by God the holy spirit.
Any materialization of what is properly spiritual dilutes the purity of emotions, faith. And especially in view of the powerful materialistic culture at present in academics, it should be forbidden.
I think this is the reason that Islam has stopped to function for many muslims, especially in the West. It doesn't work emotionally anymore, because materialistic objective notions have crept into what is properly spiritual and subjective. Even the idea of what is subjective has been corrupted with materialist notions of dopamine chemistry in the brain.
And when Islam stops working, then a typical response is to hardline the whole of Islam, to get it to work again. But I think just education on the difference between fact and opinion, would get it working again.
