1. Around 15000 years ago, Swaayambu who ruled before the present Vaivaswatha Manu, created class among the mass for ease in civilization structure (Manu Shmruthi). Brahmin : Brahmasya Gyaajuhu Braamanaha – The one knows or tries to know the Brahman is a Brahmin, he can engage in religious and teaching matters. Kshaya Athra Veeryaha : Kshathriyaha – The one who has limitless body and mind power is Kshathriya – He can guard the kingdom and the people of the kingdom from enemies; Vishyasya Sooryaha : Vaishyaha – The one is bright like sun in finance matter of the society is a Vaishya; Sha – Adhra : Shoodrha – One who can not be catagorised in the first three classes belongs to this class. All the people of the 4 classes had to go through Thread Ceremony and worship the maker. During Shukla Yajuveda period i.e during Raama’s period, i.e around 12000 years ago, in a single family, persons interested in spending more time in matters pertaining to Almighty will become a Brahmin, able bodied persons who were interested in physical fights became Kshathriyas; persons who liked to get involved in business became Vaishyas and who did not have any such above cited capabilities became Shoodras doing minial works in the society. Thus the classes were only on the basis of ability and profession and not on the basis of birth.This went on for several thousand years, but boys born to a Brahmin father liked to spend their time in matters pertaining to Almighty like their fathers, boys born to Kshthriya father liked to get themselves involved in fighting and using arms like their fathers, boys born to Vaishyaas liked to get themselves involved in financial or business matters like their fathers and boys born to Shoodhra father liked themselves to be involved in doing minial works like their fathers. Thus a classification which was started on the basis of ability slowly changed in to classification on the basis of birth. Thus a Brahmin’s son invariably became a Brahmin and engaged in religious matters, a Kshthriya’s son invariably became a Kshathriya guarding his kingdom, a Vaishya’s son invariably became a Vaishya doing business matters and a Shoodhra’s son invariably became a Shoodhra doing minial work. Hence the Classes were though basically formed on the basis of ability later changed in to classification on the basis of birth. This is the negative side of the classification. The positive side is that since father and son belonged to the same working group, improvement in all the fields were visibly noted since father will teach his sons the nuances of work. Hence outcome in all walks of life was beyond compare.
