56.57

aharniśaṃ dahed dhūpaṃ candanaṃ ca sadīpakam /
pādaśaucaṃ svayaṃ kṛtvā svayaṃ bhojayate dvijān /
dvādaśābdāni sā rājñī suvratā tatra saṃsthitā //

Day and night she burned incense and sandalwood with lamps. / Having washed their feet herself, she herself fed the twice-borns. / That queen of good vows remained there for twelve years.
