Clarifications on Israeli thought

Hello Rabbi, I wanted to start by saying that I came across your writings completely by mistake, but I couldn’t stop reading. Your messages and your statements touched me in a deep and real place, and thank you very much for that, and as far as I’m concerned, you are my Rabbi.
And now for the question, I saw that the rabbi writes in several places that Jewish thought is a field that does not exist, and I was unable to find the source where you explain this. I would be grateful if you could link me or briefly answer me why you see it that way.
