According to the Buddhist way of thinking, death, far from being a subject to be shunned and avoided, is the key that unlocks the seeming mystery of life. It is by understanding death that we understand life; for death is part of the process of life in the larger sense. In another sense, life and death are two ends of the same process and if you understand one end of the process, you also understand the other end. Hence, by understanding the purpose of death we also understand the purpose of life.
It is the contemplation of death, the intensive thought that it will some day come upon us, that softens the hardest of hearts, binds one to another with cords of love and compassion, and destroys the barriers of caste, creed and race among the peoples of this earth all of whom are subject to the common destiny of death. Death is a great leveler. Pride of birth, pride of position, pride of wealth, pride of power must give way to the all-consuming thought of inevitable death.
--V. F. Gunaratana, "Buddhist Reflections on Death"
