According to the hindu beliefs, ones position in the caste system is determined by

Karma

Explanation:

Hindus hold the belief that society is divided in different castes. This is a hierarchical structure that orders their social reality. A person's position in this system is considered to be a reflection of the accumulated merit of their past lives. This concept is known as karma. Each caste has certain rules of behaviour that they need to adhere to throughout their lives and that shape the way in which Hindu society operates.
