Spheres of life
According to Levashov’s system, there are seven spheres of self-consciousness on our planet. The most primitive inhabit in the first two of them. The most enlightened immerse all seven. Spheres have clear boundaries within which the dimensionality of space is uniform. The first two of them are called Ethereal and Astral spheres. The last two are 3rd and 4th mental spheres, where probably the most enlightened gurus of the planet are awaiting their incarnation. It has been mentioned, how an inhabitant performs himself in a physical world will define his next journey in after life. Nothing and nobody praise or punish inhabitant according to his actions. He, himself does it. You can subconsciously fee great when try to help people, or doing useful actions. Or, you overcome yourself to do bad things. The further you perform certain actions, the more you get used to it. The more you get used to it, the harder it is to turn over opposite direction. So you can be very good, or very bad depending on personality. After inhabitant has run out his physical activities and is not able to live here anymore, he goes to life after death. He will be ready to meet the afterlife inhabitants.
What exactly sphere he will move depends totally on his physical actions. Keep in mind, inhabitants of the low and the lowest spheres like astral and low astral contain creatures of extinct animals and giants that have adapted to unphysical life. It can be dinosaurs, mammoths, sort of giant monsters and all those who lost their physical identity in life and you would never like to meet them in any form. So, keep that in mind and remember everything is in your hands, yet.
