12. King Vīrabāhu having asked about the cause of his attaining the state of a Śūdra in a previous birth, the narration by the twice-born Devaśarman of the account of his attaining the state of a Śūdra due to the flaw of observing Dvādaśī combined with Daśamī, despite having previously been a brahmin, followed by the prohibition of Dvādaśī combined with Daśamī; the description that even though he became a Śūdra, righteous discernment arose in him on account of the good deed of hospitality to a brahmin in a previous birth, and therefore hospitality to guests must certainly be performed; the description by Bharadvāja to the king of the sequence of the rite for the concluding ceremony of the Ekādaśī observance; narration of the unbroken Ekādaśī observance. 203.1
