I'm using the same text I have used for this before, and I'm not a teacher.
This section is a concise explanation of Buddhist non-duality. If you want to know where the Buddhist idea of nonduality is written historically, and why it's not nihilism, this is where.
BTW, "Prakṛiti" means that which gives shapes according to this website, and Iśvara means "God" as in "Supreme Being."
