Brahmin, Kshatriya and Vaishya are born twice-once from the mother's womb and, the second time, when they attain knowledge from the Guru. They are, therefore, called dual castes. Their idol is Sun God. In contrast, the Gods of saints reside in their hearts. The Gods of people with limited intelligence exist in statues. But for very broad-minded people, the Gods exist in every particle in the world.
