Oral and Written Law, plus Physics [Modern] and Metaphysics [of Aristotle].

 Torah is not about mystical experience. However as a result of true attachment with God one can have as a side thing the experience of oneness with God. Devekut.

But it is not experience -it is a kind of  knowledge and sense of meaning.  It is what I felt in learning Torah, and it certainly is what learning Torah is all about. Yet, it is a kind of thing which has a close connection with morality. And it is on one hand highly powerful. It is the meaning of life. It is certainly not mystical experience. 

This area of value is on one hand the most powerful thing in the world and in any person's life, and yet the most delicate and sensitive and can be destroyed simply by the slightest whisper.
The approach of the Rambam --to learn the Oral and Written Law, plus Physics [Modern] and Metaphysics [of Aristotle]. There I seek the luminosity and numinous value that is hidden in the ten statements of Creation in which the light of Torah is hidden. 

[That is the Rambam himself saw that what people consider Torah alone is not enough to come to what the Torah requires of man.]

Faith plus reason had early beginnings even before the middle ages-with Saadia Gaon.

Faith in the wise is one of the 48 ways the Torah is acquired in  Pirkei Avot. The question is that of interpretation. What does the Torah mean? And who has the right to interpret it? The Talmud to a large degree has settled this question. "Divine Spirit" is not the way to interpret the Torah. Only rigorous painstaking reason as we see in the Talmud and Tosphot.

The influence of Protestantism  however is very apparent nowadays that people think they have the right to interpret the Torah on their own. This has very terrible implications. (1) Divine spirit is claimed as a guide which in practice means to ignore what the Torah actually says. (2) People claim authority though in fact ignorant  of Torah.
