What is meant by 'spiritual functions'?

The vulva is firstly and quite literally a most powerful physical channel out of which flows the special sexual/bonding energy from a woman's deepest sacred centre. This is her soul energy expressed in the form of sexual welcome to the one she wishes to give her self to in love and commitment.

Secondly, and just as importantly, the vulva is one of the most potent entry points into a woman's body-soul. Clearly women have a very deep instinctive 'knowing' that there is something special about 'down there', even though most western women in particular could not explain exactly why they feel this way. It is this primal knowledge that explains why women the world over regard their vulva as the most private part of their anatomy and are more protective of her than of any other body part. In some cultures it was and still is quite acceptable for women to go around with their breasts exposed, but very few societies will allow their women to expose their vaginal area in public on a day-to-day basis. This also explains why women are far less likely to indulge in casual sex than men. They have an instinct which tells them to be very careful who they let into their vagina, because they 'know' that they are likely to be giving them access to their soul as well.

Conversely, the truth of this fact is shown by the huge trauma that women suffer if they are raped. Rape is not just a violation of a woman's physical body, bad though that is. Much more traumatic, rape is a very real invasion and violation of her deepest sacred centre, her soul.

Note: The energy of the body-soul flows in and out via other designated parts of the body too, such as through the laying on of hands in prayer or loving touch. This is what we usually call 'the comfort of touch'. Other powerful points include the eyes. It is often in the eyes of a person that you get a glimpse into their inner self, to your comfort or at times great discomfort. Still another particularly powerful inflow/outflow point is the chest/breast area. If couples concentrate when lying naked side by side facing one another it is not difficult to feel the loving energy flowing from this area between a couple. Try it sometime!
