The most mysterious phrase of the Ra contact

[Margan]

From that same session:

"The polarity of your dimension must be internalized. Where you find patience within your mind you must consciously find the corresponding impatience and vice versa. Each thought that a being has, has in its turn an antithesis. The disciplines of the mind involve, first of all, identifying both those things of which you approve and those things of which you disapprove within yourself, and then balancing each and every positive and negative charge with its equal. The mind contains all things. Therefore, you must discover this completeness within yourself."

I think Ra refers to the balancing of the opposites. Yin - yang, in other words - we all contain within ourselves both aspects. Each male has female aspects, and each female also male aspects.
I find it fascinating, how it often shows physically as people age - some older women develop beards and may even lose their hair and older men tend to get breasts
