Question about spiritual work

I didn’t understand why you yourself agree that it is needed, and what’s more, you agree that there are things like primary concepts and essences that cannot be detailed in detail and that there are parts of them that cannot be expressed. So why do you say that there is no need for deep spiritual work, but only intellectual work… I would say that very deep spiritual work, moral and experiential, is needed before it can be expressed. In your terminology, I would say that this is what gives us the ability to perceive deeper synthetic truths, which are in any case more real. Rav Kook speaks of the deep and necessary connection between a person’s moral and spiritual state and his ability to know… It is true that this is not revealed in simple areas of knowledge such as understanding logic and ordinary analytical analysis, but it is increasingly so in areas of synthetic truths… What do you say about that?
