Kayastha

According to Hindu Vedic Scriptures the Kayastha trace their genealogy from Lord Chitragupta. It is said that after Lord Brahma had created the four Varnas (Brahmins, Kshatriyas, Vaishyas and Shudras), Yama (Dharamraj) requested Lord Brahma to help him record the deeds, both good and evil, of men, and administer justice.
According to scriptures, Lord Brahma went into meditation for 11000 years and when he opened his eyes he saw a man holding a pen and ink-pot in his hands, as well as a sword girdled to his waist. Lord Brahma spoke: You have been created from my body (Kaya) and therefore, you shall progeny be known as the Kayasthas. You have been conceived in my mind (Chitra) and in secrecy (gupta) and hence, your name shall also be Chitragupta. Brahma then enjoined him to dispense justice and punish those who violated the dharma. Thus, the Kayasthas were accorded a dual caste, Brahman/Kshatriya.
