Some folks think that the Creator is actually a usurper from the real divinity, and that therefore all of creation is inherently evil.

Lord is a word used to describe a personal relationship , like “save me my Lord” and “Ask your Lord”. Even when the Lord is being referred to the same God.

The Lord the commenter here is referring to as the ultimate Lord who has no Lord or power above him and who is beholden to no one.

In occult, the idea is to substitute your Lord from the ultimate power to the lower orders. Going back to the comment, he means to say don’t substitute your Lord for someone smaller.
