What is Reality? Consciousness notes
The Universe is infinite. In general. She has no border. It is difficult to human mind which looks for borders everywhere to present similar. However, indeed.
This Reality - one. The parallel worlds really exist, in fact are remote from us on absolutely unattainable distance (up to 10^100 km) galactic clusters.
Consciousness has no spatial restrictions. In general. It is capable to move to any point of space. As the Universe is infinite, in it there is everything. Absolutely. The uncountable doubles of our Sun remote on gugola of gugol of kilometers from each other. Each of them - with small distinction. Our world is unique, but similar to it (up to very insignificant details) - infinite number.
Now about life after death. Consciousness can separately exist from a body, and, as a rule, it happens after death. The hypothesis of an infinite cycle of regenerations - is right. All of us on this Earth to become Gods and to find so high step of Understanding to merge with those who have already reached it, having found Pansophy and Vsevedin. Transformations there can be an infinite number, and not always right after death. "The wandering souls" - not the myth, here can only move these souls without body to any point of Reality. Therefore intermundia after death and before the subsequent embodiment is, as a rule, fine. The fear of death isn't reasonable. You can move to any world voluntarily, observe any part of uniform Reality (and they very strongly differ among themselves, up to different physical constants. Nevertheless, fabric of Reality is continuous).
All religions speak to you about need of search of an enlightenment, improvement and formation by more conscious. They don't lie, and their doctrines are really useful to you. Than? Until you come to understanding of true nature of things, you are doomed to regenerating in different bodies uncountable myriads of times. But before it you have to stay some time true consciousness which in quantum sense exists and realizes itself. Behind details - to read descriptions of clinical death and an exit from a body.
As you understand, to live one more life full of pain and sufferings, pleasant it is small. You won't be able to feel pains in a "quantum" form, but you will be able to feel "sublime" pleasure (so, you can hear any, most divine music, visit the magnificent, sparkling worlds, to admire the greatest works of art). The "lowest" pleasures (feelings from tasty food, sound sleep, sexual pleasures) will be inaccessible for you.
Nevertheless, I extremely don't recommend suicide. To finish life him - means practically from 100% probability to doom itself to one more embodiment. Think whether it is necessary for you?
The most perfect and pure souls, mind realized need of altruism, moral behavior and maintenance of harmony have chance to stop this cycle and to become a part of the Absolute. In the matter Buddhists are right. But their "nirvana" not absolutely is true. This state will be found by all, absolutely. Some - through tens of thousands of the embodiments, some - after it. In this state you will feel the identity, but you will find full knowledge of everything, learn to create (more true, to find - all most unusual worlds, everything that can only come to your mind, already exists) the worlds and to carry out there unlimited number of time. This boundless happiness and feeling of Harmony when you aren't disturbed by nobody and nothing. You will be the real God in this Universe, and this Universe will be our Universe because all will have enough place in it.
About God. God exists, but he has nothing in common with what you represent him. The shortest accurate information - all of us live in mind of God, and our ultimate goal - to become one more full neuron in this chain. As I already spoke, sooner or later all living beings in this Universe is reached this state, and it will find Reason. And nothing will be chaotic in her later, everything will be subordinated to harmony in this Reality which exists eternally.
