Answer 1

The which refers to the preceding congenial state. The author is essentially saying that something can't come out of nothing, and that all things have a source.

Answer 2

The phrase "out of which" is a common construct used to indicate the origin of something. The phrase "a state out of which it has developed" means the same as "developing out of a state"
