Varna (वर्ण) is a Sanskrit word which means color or class. Ancient Hindu literature classified all humankind, and all created beings, in principle into four varnas:

• the Brahmins: priests, teachers and preachers.
• the Kshatriyas: kings, governors, warriors and soldiers.
• the Vaishyas: cattle herders, agriculturists, artisans and merchants.
• the Shudras: laborers and service providers.
