Life is a profound study that is difficult to understand. Even though human knowledge has become richer by the day, so much about life is not known. How large is life? How long can life really last? What is the color of life? What is the essence of life? It is indeed difficult for anyone to truly know.
In reality, from the Buddhist perspective of dependent origination, life is continuous, inherited, staged, and changing. For instance, transmigration between the six realms of existence, the evolving of lower-grade beings and plants into higher ones, and vice versa, are all changes.
Buddhism, it is often asked, "Where do we come from at birth and
where do we go after death? "It is similar to asking, "Which
comes first, the chicken or the egg?" In today's scientific advances,
there are many more questions on life, such as:
Nowadays, scientists studying life not only research human life. Geologists study changes of the earth's crust, astronomers the universe and solar systems, meteorologists atmospheric changes, biologists animals and plants, microbiologists the division of cells, archeologists the remains of culture and people, and historians the development of humanity.
Though life is profound and difficult to appreciate, it actually amounts to two topics: living and dying. Buddhism looks at the questions of living and dying without bias, and Buddhism itself is actually the study of living and dying. For instance, Avalokitesvera Bodhisattva relieves all suffering and resolves the problems of living. Amitabha Buddha, by receiving sentient beings to be reborn in his Western Pure Land, is resolving problems of dying.
The ultimate purpose of Buddhism is liberation from life and death. Therefore, in the study of life, we must take with much seriousness the lesson on how to make the best use of this life and be free from the cycle of rebirth.
