Quite same text you might find earlier about death, but once more here:
Sarkar: Change in the human body is inevitable, and to bring about this change, death is necessary. Death is nothing but change. From childhood… boyhood… adolescence… When an old man dies and a babe is born, it is also a change. But where the link between the preceding stage and the succeeding stage is missing, we say it is physical death.
We have seen earlier that death is only disassociation of mind from body and not the death of mind. Hence a human being’s individuality and his or her feeling of “I” will not die…Mind is the entity which acts and does not die, hence it alone will have to experience the reactions (karmaphala).
At the time of unit consciousness leaving the body, Prakrti, which is an inseparable counterpart of unit consciousness, also leaves the body. Mind, which is a creation of Prakrti, will naturally leave the body with Her.
Mind and brain are so closely connected that one cannot work without the other… A dead person’s body has a brain, but it does not function because it is dead and there is no mind in it.
Similarly when a person becomes unconscious or is made so with the help of anaesthesia, his or her brain becomes non-functional for some time with the result that the mind also does not work, as its physical base, the brain, is not fit to function. The state of unconsciousness and that of death are similar except that the former is momentary…neither unit consciousness nor mind leaves the body.
Now, what is death? After death the mind becomes suspended, and the mind and átman become dissociated from the decaying body. So on the Day of Judgement, who will rise from the grave? The body cannot rise since it has already turned into soil. And where will the bodiless mind go? Here is another point – human beings do not have to wait for the Day of Judgement, their judgement is tied to their actions. Wherever there is an action there is an equal and opposite reaction...
It (mind) had however been performing some action or other right up to the moment of death and will have to experience the reactions of those actions. In fact, it is - in order to experience these reactions and because of its inability to experience these reactions without the brain - that the mind has to take shelter in a new body in a subsequent birth. Thus it is seen that once one is born one has to face death, and that rebirth after death is also inescapable.
Hence the concept of hell or heaven where human beings are supposed to proceed after death is entirely incorrect… Pleasure and pain cannot be experienced by the mind which in the state after death is a non-functional unit, until it acquires a new brain at the time of rebirth. It is in this mortal world only that one has to be reborn to experience the pleasures of heaven and the sufferings of hell…Good (action) results for good deeds and bad results for bad ones.
If rebirth has been rationally accepted, the question of the existence of ghosts does not arise. If mind could function without a brain, it could carry on intuitional practice for the onward march towards the merger with Cosmic Consciousness in its existence after death, but that is not so. It is because of this characteristic (dharma) of mind that rebirth has to be accepted and the existence of ghosts denied and considered only imaginary.
But:…Beings that might be construed as ghosts; A devayoni is actually a human spiritual aspirant who after death, due to his or her saḿskáras, undergoes a transformation in which “… he gives up his physical structure, that is, the solid body, and gives up his aquatic structure, that is, apatattva, also, but the other three factors – tejas (luminous), marut (aerial) and vyoma (ethereal) remain with him, with his detached mind.
People who commit suicide… get the status of kabandha after death. Wherever these entities happen to see other human beings under the spell of psychic derangement, they incite them to commit suicide. Both devayoni and pretayoni are temporary conditions experienced after death.
After death Prakrti selects the proper field to suit the potential reaction. Such a field may be available in a day, or it may even take millions of years to discover it (but as the mind doesn’t function without a brain, so it can´t visit mediums either?), for the mind cannot take shelter in a body till a field which suits the requirements of potential reactions is obtained. There may be innumerable worlds where life exists. Unit consciousness and potential reactions may get a suitable field in any of them. Thus it is not even necessary that one be reborn only on this earth.
Death is necessary. Assuming that unit consciousness could continue in one body as its shelter till it gets merged in Cosmic Consciousness (no rebirth), we are faced with the possibility of one body continuing for millions of years, as the chain of actions and reactions may not free the unit consciousness earlier than that. This would result in a total stoppage of the evolution of factors in a body for millions of years.
People often hold Parama Puruśa responsible for calamities that befall them, but in fact they alone are responsible, as the suffering of fate is only reaction of their own previous actions.
All beings want to preserve their existence to attain happiness. People do not want to die, for they know happiness cannot be achieved after death. This is the main cause behind the dread of death. Thus you will find that those who do not find pleasure or happiness at all in life, and do not see even the remote possibility of any happiness, become weary of their lives and commit suicide, thinking their lives to be a burden. It is because they no longer regard life as a means of attaining happiness that they destroy it. People commit suicide for the same reason that people in normal conditions seek to destroy those factors that are detrimental and hostile to their happiness.
So, in accordance with one’s saḿskáras, one gets an appropriate physical body. If a human being constantly hankers for food, the person is bound to get the body of a pig. Similarly, if one thinks of money all the time, one will become crudified and find oneself as a safe in some bank or in the home of some wealthy individual… Human movement towards animality is not life, it is death…
It should be borne in mind that the fat stored in the human body is nothing but its work energy in latent form. When fasting or doing physical labour, it becomes liquefied, then transformed into vital energy or work energy. So when people perform little manual labour, their fat becomes their enemy and pushes them to their death.
When… anger creates its own vibrations in the mind, it exerts a tremendous influence on the nerve cells in a very short time… the flow of blood to some parts of the body increases, and the functioning of the heart is disturbed. Anger leads to premature death.
The mind will have to maintain parallelism with the physical structure while moving towards a certain object. Association by proper adjustment and parallelism between the psychic and physical bodies causes life, and dissociation under adverse conditions results in death – the body and the mind will dissociate.
There are two causes of death: physical and psychic. Physical death occurs when the waves of the physical structure become crudified due to old age or any other physical deficiency. Psychic death occurs when psychic clash with either subtler or cruder thought-waves results in increasing or decreasing the wavelength of the mental waves respectively. In this case, also, loss of parallelism will occur, and the physical and psychic bodies shall dissociate... Death can be postponed if a person’s glands are replaced…
For the vulture, the smell of the corpse is not foul, and the rotting flesh of the corpse is not harmful for its health either. But if a human being eats rotten flesh, his or her death is inevitable.
The only way to do service to one’s mother after her death is to help every female member of the universe to progress on the path of highest development.
The moment a man is born he starts his journey. The end of his journey is death. The gap between these two is life. It is a small gap. Waste no time. Every minute takes you nearer to the grave. This mission of life – to be one with God – has to be fulfilled here and now. And that’s why when one is ensconced in that supreme centre; one establishes oneself beyond life and death…one is established in immortality. Death will not be painful for you, because in death too you attain Him. Merge with Him with all your love. By knowing Him alone one overcomes death.
Some other kind of deaths from Sarkar:
Communism has already died a premature death while still in the stage of youthful vigour, but when capitalism dies it will die a mature death.

So why capitalism has to die? It has lived its time, achieved what it suppose to, and humanity - while developing spiritually - needs now something better, thus Prout is based on spirituality.
