Reincarnation and Rebirth are central beliefs of Buddhism. The concept of reincarnation and rebirth is that people are reborn after dying.
Buddhists believe that individuals go through many cycles of birth, living, dying and rebirth. A practicing Buddhist can differentiate between both concepts of rebirth and reincarnation.
In Reincarnation, the individual returns as the same entity and may recur repeatedly. In rebirth, a person does not always return to Earth as the same entity, ever again.
Buddhists compare it to a leaf growing on a tree. When the dying leaves fall off, a new leaf will eventually replace it. It is similar to the old leaf, but it is not identical to the original leaf.
“If you look deeply into the palm of your hand, you will see your parents and all generations of your ancestors. All of them are alive in this moment. Each is present in your body. You are the continuation of each of these people.”
― Thich Nhat Hanh
