I love this article because Tantra is far older than India. I have always said this and I do know that most all ancient civilizations practiced sacred sex… Check this article by Drunvalo.
Sex, and specifically the orgasm, is more that just something that feels good and allows procreation. There are many other functions, such as the release of dysfunctional energy within the body, which can help to keep one from becoming diseased. There is the function that opens the higher chakras, and under the right conditions allows a person to begin the process of enlightenment. And further, if two people, lovers, practice sacred sex, the entire experience can lead them together into higher consciousness and into worlds beyond this plane.
In relationships, a simple sexual principle, as taught by the ancient Egyptians, can change the energy level within your body and help to bring strength and vitality into your bodies and your relationship.
The full subject in detail of Egyptian Tantra is incredibly complex, and cannot be completed in an article of this scope. But we can speak of the heart of the matter — the human ankhing experience as practiced by the ancient Egyptians.
And so, adapted for our readers from The Ancient Secret of the Flower of Life, Volume II, I offer this insight to assist two lovers — or even yourself, alone — to begin to find the higher path. This practice will not directly show you the true path. But it will increase your life-force energy, making you stronger, more alive, and more conscious. And perhaps — if you believe the Ancient Egyptians — it may lead you into eternal life.
