or Urdhvareta. Sanskrit; urdhva ,"upwards" + reta, "seed" thus literally meaning to send the seed upwards.
"In India, sexual magic (Arcanum A.Z.F.) is known by the Sanskrit term “Oordhvareta [Urdhvareta].” People who practice the Arcanum A.Z.F. in India are called Oordhvareta yogis. The Great Arcanum is found in a Hindustani book entitled Secrets of Yoga. The author is a yogi from Southern India." - Samael Aun Weor, The Yellow Book
A perfect initiate whose sexual fluid is completely sublimated.
"An Oordhvareta Yogi is one in whom the seminal energy has flown upwards into the brain as Ojas Sakti. There is now no possibility of the semen going downwards by sexual excitement." - Swami Sivananda
"According to Yogic science, semen exists in a subtle form throughout the whole body. It is found in a subtle state in all the cells of the body. It is withdrawn and elaborated into a gross form in the sexual organ under the influence of the sexual will and sexual excitement. An Oordhvareta Yogi not only converts the semen into Ojas, but checks through his Yogic power, through purity in thought, word and deed, the very formation of semen by the secretary cells of the testes or seeds. This is a great secret. Allopaths believe that even in an Oordhvareta Yogi, the formation of semen goes on incessantly and that the fluid is reabsorbed into the blood. This is a mistake. They do not understand the inner Yogic secrets and mysteries. They are in the dark. Their Drishti or vision is concerned with the gross things of the universe. The Yogi penetrates into the subtle hidden nature of things through Yogic Chakshu or the inner vision of wisdom. The Yogi gets control over the astral nature of semen and thereby prevents the formation of the very fluid itself. The body of a man who is truly an Oordhvaretas has the scent of a lotus. A man who is not a Brahmachari, in whom gross semen is formed, may, on the other hand, smell like a buck goat. The semen dries up in those who practice Pranayama seriously. The semen-energy ascends up to the brain. It is stored up as Ojas Sakti or spiritual energy and comes back as Amrita or nectar. The process of sex sublimation is extremely difficult. It demands constant and protracted Sadhana and perfect discipline. That Yogi who has achieved perfect sublimation has perfect control over lust. Complete sublimation is achieved through ceaseless meditation on Atman and Self-realization. That Yogi or Jnani who has attained the highest Nirvikalpa Samadhi, in whom the seeds of Samskaras are fried in toto, can claim to be a perfect Oordhvaretas or one who has complete sex sublimation. There is no fear of his downfall. He is perfectly safe. He will be absolutely free from impurity. This stage is a very high stage. A microscopic minority only have attained this sublime exalted state." - Swami Sivananda
