2. "The disciple must not let himself fall, because the disciple who lets himself fall has to fight a lot later to recover what was lost. The one who ejaculates the ens-seminis loses the fire... In the spinal cord there are 33 vertebrae that are closely related to the 33 degrees of occult Masonry. As we practice the Sahaja Maithuna, the sacred fire ascends slowly, from vertebra to vertebra, that is, from degree to degree. When we make the mistake of ejaculating the semen, then the fire descends one or more vertebrae, depending on the magnitude of the fault." https://glorian.org/learn/courses-and-lectures/lectures-by-samael-aun-weor/the-aquarian-age-and-the-purpose-of-sex
