First I would like to express my sincere gratitude to all who make this online sangha possible. I am so glad I joined treeleaf Zendo. I am immersed in going through all the talks and teachings by Taigu and Jundo regarding basics on Zazen, Zen Buddhism. I find myself immersed in a brand new flavor of Buddhism and associated things that I have NO knowledge of. I am wondering if there is anywhere on this site that explains some of the spices in this stew?

For example, what is a rakusu, taku, and all these other wonderful things/traditions I am looking at? ASSUME I know nothing and you are off to a good start.

I don't need a drawn out answer if there is a simple source to point me to
