Forget all of the myths, they were meant to hide the real meaning.

Bring your inner state out into the world. Be outwardly what you are inwardly.

From The Gospel of Thomas:

Jesus said, "If you bring forth what is within you, what you
bring forth will save you. If you do not bring forth what is
within you, what you do not bring forth will destroy you."

Inner does not mean what you feel. Feelings have nothing to do with high spiritual consciousness. Whatever feelings you might have will be the result of having had the experience, with the exception of joy. High spiritual consciousness is Peace.

You can be a warrior in the midst of battle and still be at peace.

Therefore, bringing the inner into the outer is to express the Peace of your inner being.

How do you DO this?

By laying your hands on another person and administering a blessing. By getting out of the way and letting Spirit move through you, you are letting the innermost part of you out into the world.

***Acting from within, you wed your inner being (God) to your outer personality.***

Once you have mastered or even achieved a level of proficiency at living from an inner state, the Sacred Marriage begins. As in all initiations, it is a beginning. It doesn’t come all at once. That would be too disorienting.
