First, I tell you how this idea was born. I am experienced in meditation about 9 years. My goal was to reach nirvana. And once it happened. I sat in a room and saw a matter around me like non-existent. Then I saw a huge dark black hole with huge gravity around. My mind disappeared and only dark hole was present. I clearly saw like all around world, all matter was like illusion, even a sunlight was an illusion. In other words, matter does not exist at all. My mind was shocked, how it is possible ? Then I started to understand, it was not a hallucination. Abot 3 years I explored in meditation what a nirvana is. First, nirvana is not only a state of a mind. It is really something, that is present, it is that exists, some kind of substance, Our matter is opposite to nirvana. Second, it is not something horrible, but opposite, it is very peaceful, silent, immovable, there is no any danger. If I see it, If I feel it, there are must be some methods to reveal it in a scientific way. to explore. If anybody who is really is interested in this work, i can send material evidence of nirvana, and description, how to create mini-lab of nirvana.
