Unfortunately I do not know what post you're referring to. We tend to post a lot on the forum and can't keep track of everything!
However, to clarify the quote above, the black lodge is necessary for the development of objective knowledge within the initiate, but the problem is that our humanity has developed way too much ego! The black lodge will always exist in the universe, as evidenced by the symbol of Yin and Yang, but sadly these sorcerers of the left-hand path justify their ways, ignoring that they must renounce their desires if they want to become angels!
