Any Jewish mystical commentary on the Tanakh?

Hello. Apologies if this is a silly question to ask.

I’m not Jewish but I am interested in learning about mystical practices from all religions.

I am not sure how reading the Tanakh works. I’m using this site:

https://www.sefaria.org/Genesis.1.7?lang=bi&aliyot=0

from what I understand the Tanakh is often read alongside commentary. But also different commentaries serve different purposes. I was wondering if there are specifically jewish mystical commentaries?
