Modes Of Birth And Death
Buddhism assesses death to the following four causes:
1. The exhaustion of the force of Reproductive Kamma that gives rise to the birth in question - Kammakkhaya.
The Buddhist belief is that, as a rule, the thought, volition, or desire, which is extremely strong during lifetime, becomes predominant at the point of death and conditions the subsequent birth. In this last thought-moment is present a special potentiality. When the potential energy of this Reproductive Kamma is exhausted, the corporealised, the life force, cease even before the approach of old age.
2. The expiration of the life-term - Ayukkhaya.
What are commonly understood to be natural deaths due to old age may be classed under this category. There are various planes of existence according to Buddhism, and to each plane is naturally assigned a definite age-limit. Irrespective of the Kammic force that has yet to run, one must, however, succumb to death when the maximum age-limit is reached. It may also be said that if the force is extremely powerful, the Kammic energy rematerialises itself on the same plane or in some higher realm as in the case of the Devas.
3. The simultaneous exhaustion of the Reproductive Kammic energy and the expiration of the life-term - Ubhayakkhaya.
4. The action of a stronger Kamma - Upacechdaka that suddenly cuts off the power of the Reproductive Kamma before the expiry of the life-term.
The first three types of deaths are collectively called Kalamarana (timely death) and the last one is known as Akalamarana (untimely death).
An oil lamp, for instance, may get extinguished owing to any of the following four causes:- the exhaustion of the wick, the exhaustion of oil, simultaneous exhaustion of both wick and oil, and some extraneous cause like a gust of wind.
The death of a person may similarly be caused by the above-mentioned four ways.
