During those periods, there were no casteism. Manu had divuded the Universe into four parts as listed below :
1. Brahmin : Who use to give the Knowledge ? 2. Shatriya : Who use to do war ? 3. Vaishya : Who use to do the Business ? 4. Schudera : Who use to do the physical work of any form ? Men was defined by their action during those days. A person borned in Brahmin family started doing physical job, will not called Brahmin, he will be called Schudera. This was a basis practice at that time. Now a days, the whole context is changed and selfish analysiation has been given to the society by the politicians for fulfilling their selfish interest for vote bank politics only. New definations has been created.
