It is a growing experience. Reincarnation is just a path of life. It is there as a fact of life, a way of life. It is the same as breathing. You breath in life, you breath out death.
Day is like life, and night is like death.
The two make one. Each life that you live is a growing experience. It is a balancing effect. In this life you do, in the next life you get. But you are always getting and doing simultaneously.
