Death is a progressive process of the dissolution of body and mind that can be divided into eight main stages. As the body deteriorates, the energy required to sustain sense consciousness such as our eye awareness, then course conceptual consciousness - thoughts and emotions - and finally subtle consciousness is lost. At the same time there are specific signs or appearances to mind that mark these eight stages. The last stage being called the Clear Light of death or Mother Clear Light.
The point at which this Clear Light of death becomes manifest is of vital importance in a meditators life, as it is at this stage that one’s meditation can herald deep realisations into the nature of reality and propel a yogi along the path to enlightenment in very short period of time.
Also from an ordinary point of view, when death comes to an ordinary human it comes in a series of dissolutions. Since we will all face this process at some point, it is seen as important to understand the death process, if only to not let oneself fall subject to fear and so forth.
The Mind at Death
It is said that the state of mind of an ordinary being at death plays a large role in determining the type of rebirth that the being will take. Therefore it is very important to die with a positive state of mind. Therefore it is very useful for the dying to practice meditation, practice generosity by giving away their belongs, and saying goodbye to loved ones.

These 25 gross/course objects constitute one way of enumerating our mind-body complex.
The dissolution process as stated earlier can be presented in 8 stages.
In the first four stages there is the simultaneous dissolution of a group of the 25 gross object from the list above. Don’t think of this process as one thing dissolving into another, it is more like the power of one group can no longer operate and so another becomes manifest. At each stage there is both an internal sign and an external sign associated with the dissolution of the various elements of the body and mind.
The Dissolution Process
The First Stage:
Simultaneous dissolution of the form aggregate, the basic mirror-like wisdom, the earth element, the eye sense and visible forms.
Internal sign - Mirage like vision.
External sign - the body withers, sights become unclear, and there is a feeling as if the body has become heavy.
The Second Stage:
Simultaneous dissolution of the feeling aggregate, the basic wisdom of equality, the water element, the ear sense and sounds.
Internal sign - Smoke like vision.
External sign - Feelings of pain and pleasure associated with the body are no longer felt. The bodies liquids dry up and sounds can no longer be hearing, including the buzzing in one’s ears.
The Third Stage:
Simultaneous dissolution of the discrimination aggregate, the wisdom of analysis, the fire element, the nose sense and odours.
Internal sign -The vision of sparks against a dark background.
External sign - The name’s of people and objects can no longer be remembered. The body loses it’s heat, and so the power to digest food is also lost. Exhalation of the breath is stronger than inhalation, and breathing becomes more difficult. The ability to smell is also lost.
The Four Stage:
Simultaneous dissolution of the compositional factors aggregate, the wisdom of achieving activities, the wind element, the tongue sense and taste.
Internal sign - flickering light, like a very small candle.
External sign - Breathing has stopped and all ability to move has been lost. Because the wind element has dissolved and therefore the breathing has stopped in the west most people are renounced dead at this point. But according to Buddhism death does not occur until the mind has left the body which is sometime after the 8th stage.
The Fifth Stage:
Gradual dissolution of the eighty indicative conceptions and the mind of White Appearance. As the mind of White Appearance becomes manifest a vision of pure white light is seen. It is said that at this point, the mind is empty of all conceptuality other than the mind of White Appearance.
As the mind of White Appearance loses it’s power, the Mind of Red Increase becomes manifest.
These appearances occur as the subtle energies of the subtle body (nervous system) are lost. or dissolve into one another.
The Sixth Stage:
The mind of Red Increase is a vision of redness, like a bright sunset in summer. At this point the mind is empty of all conceptuality other than the mind of Red Increase.
As the mind of Red Increase loses it’s power, the Mind of Black Near Attainment becomes manifest.
The Seventh Stage:
The mind of Black Near Attainment is a vision of complete darkness or blackness. At this point the mind of empty of all conceptuality other than the mind of Black Near Attainment.
As the mind of Black Near Attainment loses it’s power, the Clear light of death becomes manifest.
The Eight Stage:
Clear light of death is an experience of the pure radiance of the mind. This experience is of complete clarity and awareness, it is the most subtle aspect of the mind and is that which all phenomena manifest. A yogi can meditate on this mind for weeks.
The Actual point of death
One can still recognize if someone is alive at this point by whether or not there is any heat remaining at the point of the heart - the centre of the chest, not the physical heart. Once the mind leaves the body - the actual point of death - the heat at the heart will be lost.
