Another spheres of life
According to Vedic system, there are seven spheres of life and 7 self-consciousness planes 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 afterlife.
Nothing and nobody praise or punish inhabitant according to his actions. He, himself does it. You can subconsciously feel great when try to help people, and doing useful actions. Or, you overcome yourself to do bad things while feeling yourself guilty. The further you perform certain actions, the more you get used to them. The more you get used to it, the harder it is for you to turn over into the opposite direction.
There are all types of spheres of life out there. You can find yourself useful in any plane that resonate with you most. Or you can move any direction you like. It’s all the matter of a choice.
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 the afterlife sphere where witnesses the death. He will be ready to meet the afterlife inhabitants as well. Some of them are nice. The others are not really.
What exactly sphere he will move into depends totally on his physical actions. The actions that pick his next destination. Keep in mind, inhabitants of the low and the lowest spheres like astral and low astral plane 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 this plane and you would never like to meet them in any form. So, keep that in mind that spheres of life directly affecting our existence and everything is in your hands.
