Learn the practical science to work directly with the root energy of all existence, and experience for oneself the reality of the ancient and mysterious Divine Mother Kundalini, spoken of in all the world’s great religions as Isis, Mary, Maya, Cybele, Ima, Hera, Shakti, Durga, Athena, and countless more.
Her most sacred science is protected in the secret heart of every religion: the upright use of sexual energy, harnessed with love and ethical purity. When followed with precision, sexual yoga awakens her divine intelligence in us, called Kundalini in Asia, and in the West, the fire of the Holy Spirit, the fire of Pentecost. Includes many practices of meditation, transmutation, astral projection, pranayama, and the long-hidden Jinn Science.
