Daulat Rai's preface to his book on Guru Gobind Singh

I have come to this world for this purpose, The Supreme Lord has sent me for the protection of Righteousness,: You should propagate righteouness everywhere,; seize and destroy the sinful and the wicked. I have taken birth for this purpose, let the holy men understand this in their minds. Ihave come for spreading Divine Religion, and for protection of saints, and for annihilating all the tyrants. (42-43/6)
