(Sanskrit; alternately urdhvareta)

"A Yogi always directs his attention to the accumulation of this divine energy by unbroken Chastity. In Yoga , it is called Oordhvaretas. 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, Practice of Brahmacharya

"The great Yogi-Avatar Sri Lahiri Lahasaya was called to the Initiation by the immortal Babaji when he already had a spouse. Thus, this is how the Yogi-Avatar was Self-realized. In Hindustan, Sexual Magic is known by the Sanskrit term Oordhvareta and the yogis who practice it are named Oordhvareta Yogis. Authentic yogis practice Sexual Magic with their spouse. There are two types of brahmacharya (sexual abstinence), solar and lunar. The solar type is for those that have performed the Second Birth. The lunar type of brahmacharya is that absurd sexual abstinence that serves only to produce filthy, nocturnal sexual pollutions with all of its fatal consequences... The yogis who practice Oordhvareta Yoga (positive Sexual Magic) do not ejaculate their Ens Seminis." - Samael Aun Weor, The Esoteric Course of Kabbalah
