People who follow Hinduism live their live by following the Caste System. The Caste System is a classification system used by almost all of India. where you are classified is based on whether or not your karma was good or bad in your past life. If your karma was good then you will move up in the system. If it was bad then you would move down. The goal is to become Brahman, or a god that is perfect. If your karma that is very bad, you can move down so low that you are reincarnated into an inanimate object, like a rock or a plant.
Reincarnation is the belief that when the body dies the soul moves into another being. Buddhists also believe in reincarnation.
Hinduism affects the India culture by getting the people to try to live an ethical lifestyle in order to become Brahman. The people give more than they may usually give. Also they get to know their community better because in the Caste System, the different classes do communicate or interact with each other at all.
