While the human creation is through the divinely controlled evolution, it is important to understand that this is not the only process by which life is created by the agencies of God in accordance with the divine mandates!
At the same time, human mind is not created with any slavish submission to its creator. Human mind is divinely mandated as free-willed. Humans are capable of rejecting or accepting divine guidance!
Human body is not immortal. Inherently, humans and all material living beings are mortals. In other words, they are with material bodies that has an end. Its life span is limited. Every human has a unique personality and this personality is both inherent and acquired. Personality has several characteristics. Both personality and life are unique gifts from God-the supreme source of everything.
Human personality can potentially survive material death under certain conditions. Thus all human personalities do not survive after their death. Plants and animals have certain limited functions on earth. Those humans who do not survive death are also similar in nature.
Human mind becomes immortal soul with a unique personality when the human mind fully fuses with the god-fragment that resides within the human mind as a separate entity. This god-fragment is that enables the human personality to survive death and live again in another phase of existence. But the fusion of human mind and the god-fragment within can happen only when the human mind is decisively oriented towards God's will.
Whether a human being is potentially a survival candidate is not determined by the individual concerned. It is a function of certain universal agencies of God. A human mind with potential fusion capability with its god-fragment need not get aligned for fusion very easily. This process might take much time and might undergo several mind polishing processes. Such minds may be allowed to take re-births in different bodies till the mind polishing is complete.
Thus re-births are a fact. But all humans do not undergo re-births. Again, re-births for a man or woman on earth would not be on earth again. It would be in another planet or planets far away in the cosmos. Such a planet is a kind of heaven because these kinds of dwelling places are not evolutionary planets like earth. They are specially made planets for polishing and upgrading humans of survival potential after their initial material life and death on earth.
Even while having their new lives in those heavenly planets of marvelous creative beauty, some human minds may refuse to align with God's will which prevent their personality fusion with the god-fragment. In this case they may not face with death again, but face another situation. They fail to progress to higher levels of perfection and universal adventure. They remain where they are. Eventually, it might be like prisons for them. Such places of detention in the universe are the so-called 'hells'.
Aligning with God's will and surviving physical death for advancement in the universe career of everlasting life and adventure is not much difficult provided humans are sincerely willing reject evil ways of living and adopt life that is essentially in accordance with divine mandates.
Divine way of living essentially means a sincere desire to be god-like by enhancing godly qualities of love, compassion, honesty, creativity, patience, humility and above all with a desire to love the invisible Supreme God of all creations as a parent. A perpetual and willful rejection amounts to an evil way of living!
Fusion with the Universal Soul (Param Atman) and going beyond consciousness for achieving what is known as ' Moksha' or salvation is an erroneous concept. If that could have been the desire of God, there was no point for Him to create intelligent humans! Essentially, by creating humans through the process of controlled evolution, God has been attempting a unique creative method to develop extremely useful beings for universe administration. That is the creation of time-tested experiential beings who are required for certain kinds of universe administration.
Humans on earth and similar earth like planets elsewhere in the universe are essentially immortal beings under the process of creation! When their creative development go wrong, they cease to exist or their further development is curtailed. Otherwise they develop fully to become time tested immortal beings of remarkable utility for God.
I hope you now understand what happens after death to some extent. I also hope you could better appreciate the teachings of our existing religions as well.
