"This kind of knowledge is spread all over the place. Some of it is documented in texts, some are transmitted through traditions."
“It’s hard to distinguish what is true and what is bogus.”
Guruji: “Yes, only with experience you can tell what is possible and what is not. It’s a research work.
"There was a pundit in Mathura who had gained control over a yakshini (a powerful ethereal being). There are lots of ways described in tantras to gain control over different kinds of yakshinis.
"He could do miracles with the help of that Yakshini, like being able to tell anything about anybody, causing hail-storms, raining of stones, etc. But when he was about to die, he realized the terrible consequences he was going to suffer. So he called his sons and told them this ‘I’m sending her to a far-off place. Before she returns, tie my body to a heavy stone and drown me in Yamuna river, otherwise she’ll take me with her’. See that’s the point. If you enslave an astral being for material gains, you won’t be able to get away from it after death. They are powerful in that domain! You force them to be a slave against their will. If she had served him out of her own will, it would have been perfectly fine.
“So he sent her away and before she could come back, he drowned himself in the river. What happened afterward is just unimaginable! It rained blood in their house, his dead body when recovered was found filled with human feces in the mouth! It was unmentionable what all happened to them. That’s why the wise men have said ‘Beware! All such businesses have a terrible end.’ You get some publish adulation but ultimately suffer the consequences yourself.
“Guruji, what do these ethereal being generally do?”
Guruji: ‘Well, these ethereal beings have a totally different sense of time from us. What a lifetime is for us could be just a day or two for them. And they have very long lifespans – thousands and even millions of years long. They live very long!
“If people know about these terrible consequences, why do they do these things – force ghosts, yakshinis, etc, to do their bidding?”
Guruji: “For greed, for fame, public adulation, for earning money, doing business, impressing people, what else! Feeling of power is very intoxicating. Everybody wants credit for doing favors, everybody wants people to sit at their feet and worship them as gods. All these things lead people on these paths."
“Guruji, are there any tantric practices in our yoga tradition as well?”
Guruji: “No, we don’t have a system to force anybody against their will. They can contact us on their own, and they do. That is a better option, if there’s friendship on an equal footing. Remember, friendship lasts only among equals. When you are able to raise your standards to their level, they’ll automatically contact you. Before that, it’ll be forced.
"Even this name you must have heard, Mahamahopadhyay Gopinath Kaviraj. He went mad in the end! He also developed rectum cancer. Anandamayi Ma took care of him in her hospital. He was trying to gain control over a yakshini. That ritual failed and he went mad and died as if he was suffering in hell! He had a really terrible death.
"Think of it this way – you are blackmailing a very powerful person to do your bidding. The day you loose your hold, he’ll destroy you. And when you deal on equal terms and you yourself have become powerful, there might be a friendship. That has always been the difference and will always remain so. And self-progress can only happen through Yoga; there’s no other way. Self power can only increase through yoga. And the purpose of Yoga is always perfectly clear! Instead of catching some other spirit to gain knowledge about the spiritual world, why not control your own spirit and gain that knowledge – didn’t it also come from the spiritual domain? And you don’t blackmail yourself.
