It is commonly said that human beings do not know about death, since nobody has come back to tell them about it. Of course, this is false. Many people have apparently died and been revived, and their reports are very revealing.
Likewise, many reliable individuals devoted to one or another form of Spiritual practice have enjoyed, and subsequently communicated about, the subtle and (beyond the subtle) the Transcendental aspects of human existence, all of which relate to the process of death and one's destiny beyond it.
What people truly mean when they say they do not know about death is that they do not know exactly what will follow it in their own case. Yet, the generalized presumption of no knowledge about death only provides an emotional excuse for avoiding the inevitable confrontation with the reality of death and the necessity that one study it and prepare for cooperation with its process.
The process of death — like all the common events of human experience — is clearly available for you to observe in others and to study, as a common (as well as a personal) psycho physical event.
You can and must prepare for that event, even as you normally prepare for other great events — such as childbirth, or an operation, or a test of knowledge and skills relating to a profession.
Just so, like every human individual, you have many experiences during your lifetime that clearly duplicate at least some of the psycho physical aspects of the death process. These include the regular act of going to sleep, the experiences endured during periods of illness, and (if you are involved in Spiritual practice) the progressive revelation enjoyed via a lifetime of meditation.
Also, many people are given remarkable experiences that reveal and demonstrate to them the actualities of the death process. I Myself have had many such experiences — including complete duplication of the death process.
Therefore, you should not presume that you do not and cannot know about the death process. You can and must know about that process, and you must prepare for it through psycho-physical self study.
Even if you do not come to know in advance exactly what will follow your own death, you can know about the death process itself, since it involves the familiar processes of your present body mind.
Furthermore, you can (while still alive in this world) enter into the profound practice of esoteric Spirituality, by means of which it is possible to Realize the Real Condition of Existence (Which Is your Ultimate Destiny), as well as the actual structures of your experiential existence.
