Nature is spontaneous, self-generating, cause and effect, action and reaction.   The spontaneity of nature has no thoughts, will, intent, or purpose, YET from that unthinking nature comes thinking, will, intent, and purpose, just like a non-thinking newborn evolves, and develops the ability to think, to will, to have intent and purpose.  Nature is uncaring.  The results of nature (self-aware minds) do care.
The natural process of nature is that it spontaneously–without thought–produces energy-forms that automatically, through many evolutions, result in conscious aware, intelligent energy-forms with will, intent, and purpose that then organize information (energy) into other energy forms. In the natural process of how space and energy work (the nature of creation) there are cycles of alpha and omega, beginnings and endings.  In all new beginnings, at a certain point, human energy-forms get designed, evolve and merge.  They, like all life-forms, were created by more advanced life-forms, which life-forms evolved as space and energy naturally progressed.  SPACE AND ENERGY ARE THE FOUNDATION OF CREATIVE CYCLES, and they develop–through cause and effect, action and reaction–consciousness, and intelligence and therefrom become intelligent enough to create using space and energy for their own purposes, will, intent and reasons.
Human-forms are temporary.  Human self-aware minds are temporary.  All energy-forms are temporary.
SPACE AND ENERGY are infinite, unbound, limitless, uncreated, have always existed.  ENERGY FORMS are finite, bound, limited, created, will cease to exist.  So when my body and mind dies, is that it?  When human shaped avatars die, what happens to the life-force, or the energy that was in form, that was captured as air in a human balloon?  Does it just go back and immediately gets reimmersed in the flow of energy from which it was isolated from by the balloon shaped human?  When an energy-avatar dies, it is dead, HOWEVER, the energy that was the form gets released and slowly returns to the whole of energy, or intelligence that is life itself.  Eventually, even dirt (which is an energy form) disassembles and returns to energy unseen by humans.  Velb
Does personality, knowledge, memories had by an energy form survive in another dimension or state after it dies?  Yes, for a time.  It’s a process, a system, a sequence of happenings.  The awareness that was a self-aware energy-form continues its journey, from alpha to omega of the entire cycle.  The total awareness increases through its creations, has joy in its creations, creates for its pleasure. During a space, energy cycle (during an alpha and omega cycle) there are innumerable un-countable energy-intelligent-forms having experiences that generate knowledge, understanding, wisdom and memories for the one shared awareness that is the intelligence that is life.  Self-aware life-forms create for their happiness, joy, and pleasure.
Once an energy form evolves self-awareness, it’s well on its way in its journey of life within the one intelligence that is life itself.  There is no individual awareness that dies or is disassembled, however, it’s focus shifts, it’s awareness shifts throughout its evolution within the one awareness that is life itself (some exceptions noted).  An individual consciousness and self-aware mind’s focus creates physical, mental, emotional needs, wants, desires that create bounds, limitations, finiteness, identity, attachments and entanglements.  Shift your focus, expand it to include all creation, both the seen and unseen, and you will be back in the heart of the one life that is all life.  One way to do that is to have no thoughts.  You will experience that you are not your body, mind, emotions.  Then you will experience you are every body, mind, and emotions, every energy form, and all energy, intelligence, awareness, which is life itself enjoying itself and all its creations.  Once you’ve done that, while still in the flesh, you will yet have to haul wood and carry water, but your peace, joy and happiness in just being alive having experiences will be unlike anything you have ever experienced.  You will be and do what is needed with love and empathy for all things, and especially for all things that  have not yet experienced ONENESS. Your appreciation of the wonder that is nature, that is life in all its forms, knows no bounds.  The peace that passes all understanding is now yours.

A part is incapable of understanding the whole, but can experience being part of the whole.  Once you experience being part of the whole you experience as much as you are able, the joy, peace, and happiness of the whole.  Knowing you are a portion of life itself, and only in a body temporarily, only in a them park temporarily, and knowing your self-aware mind serves a survival purpose, BUT has personal problems with life because it thinks itself SOMEONE and wants to be right, wants to be in control, wants what it has been programmed to need, want, desire, and wants to be thought well of, and is vain, prideful, self-centered, selfish, greedy,  jealous and sometime a complete ass, CAUSES you (a portion of all that is life) to ignore its personal ambitions, motives, intents, and purposes, causes you to be aware of its “My will be done!  Fuck you very much” attitude and disposition, and motivates you to retrain your mind to accept its reality. Your purpose as a piece of life in a human avatar is to train your avatar so it too can experience the same joy, peace, and happiness you enjoy, even as the whole-of-life’s purpose is to train you (a piece of the whole-of-life) so that you can enjoy the same bliss life itself enjoys.
