Gnosis is not a doctrine that seeks to convince skeptical people, because if today we convince 100 skeptical individuals, tomorrow we have to convince 10,000, and if we convince the 10,000, then 100,000 will appear who want to be convinced, and so on and so forth, thus, we will never be done." -Samael Aun Weor, Key of Sol
This science is not for skeptical people. Such people are useless for Jinn Science. This science should never be exhibited, for the White Lodge forbids it. Jinn Science is not to be displayed or demonstrated as a spectacle of magic. This science is terribly divine and can be practiced only in secret. When I, the author of this book, wanted to publicly demonstrate Jinn Science, the Master Morya immediately intervened by saying: “We have been teaching and helping you for the past ten years and now you want to exhibit your powers. Why? Powers are very sacred. Powers must not be exhibited to the public.”
Since then we have understood that the Jinn Science is very secret. Many people would like to see demonstrations. We, the brothers and sisters of the temple, are not experimental animals of a laboratory.
The truth is what one experiences within oneself. We cannot experiment with other people’s bodies.
We give the keys so that each one can experiment this with their own flesh. We do not advise people who are filled with doubts—skeptical ones—to enter into these studies, because they may go mad. The battle of tremendous contrast and opposition can destroy the brains of the skeptics; this may force them into a mental institution.
Therefore, Jinn Science is for those who have unbreakable faith, like steel. This science is not for people who are full of doubts. - https://glorian.org/books/the-yellow-book/jinn-state
Why do spiritual organizations ask for donations? So people have a way to sacrifice for others, and pay their karmic debts.
Moreover, Glorian has no interest in reaching the masses. The masses do not want this knowledge. This knowledge is for the few who want to change.
Regarding not having experiences, perhaps your focus could be better directed. Which would you prefer: to perceive other dimensions, or to stop causing pain? Those who are focused on having experiences will have them, but they will not be capable of using them effectively, because they did not change. Those who are focused on stopping the causes of pain will also have spiritual experiences, but their psyche will be capable of taking advantage of them in an upright way. My advice is to crush the egos that demand "spiritual experiences" as proof, and instead look for proof in the changes that this knowledge can create in your mind, heart, and actions.
