“ ‘From the mouth of Brahmā, the brahminical order has come into existence. Similarly, from his arms the kṣatriyas have come, from his waist the vaiśyas have come, and from his legs the śūdras have come. These four orders and their spiritual counterparts [brahmacarya, gṛhastha, vānaprastha and sannyāsa] combine to make human society complete.
