There are two famous reincarnation system of Living Buddha in Tibet – Dalai Lama and Panchen Lama.
According to the ancient Indian books, it is said that the life is interminable. The endless life could come again and again in different bodies. After the death of one body, the body comes back to the boundless life.
The Buddhism combines the personal behaviors and the destiny together forming the system of retribution. It says that whatever the things people do in his life, there is going to be retribution in his next life. For example, you do good things when you alive then you will get good destiny in your next life otherwise you will get a bad suffering in your next life.
The Buddhism thinks the retribution is caused by the personal desire. Thus people believe in Buddhism to extricate the life Samsara, which is the only one solution for getting away from the suffering.
There are some differences between the Hinayana and the Mahayana of Buddhism.
The Hinayana thought that it is a personal case about getting away from the suffering to believe in Buddhism.
The Mahayana insists that everything of the world combines together such as human beings, between people and other animals, the people and the nature. They affect each other during the life, thus it is formed an extensive causality of retribution.
For example, if you do the bad things, you won't extricate even you died. Only all of the living creatures been extricated, you will get away from the suffering at that time.
Therefore, the view point of the Mahayana cam explain the difficult problem of the globality of the world. The personal behaviors affect other people and the environment surrounded and so on. We everybody will get the corresponding destiny in our next life whatever we do. The theory could related with environmental pollution, ecological balance, AIDS virus, nuclear war and the population explosion and so on.
The reincarnation system of Living Buddha means the soul will be alive in different bodies the same as the theory of the Mahayana's. According to the Tibetan Buddhism, the Living Buddha is the great enlightened one who will help people get way from the suffering all the time.
