Living in cupidity and arrogance, they refuse to treat their seniors and aged men with love and affection, even insulting those that deserve to be honoured and asserting their superiority over them without showing reverence and humility. Such men, O goddess, sink in Hell. When their sufferings come to an end after a long course of years, they rise from Hell, and take birth in the order of humanity, in low and wretched families. Indeed, they who humiliate their preceptors and seniors, have to take their birth in such castes as those of Swapakas and Pukkasas who are exceedingly vile and bereft of intelligence. He who is not arrogant or filled with pride, who is a worshipper of the deities and Brahmanas, who enjoys the respect of the world, who bows to every one that deserves his reverence, who utters smooth and sweet words, who benefits persons of all orders, who is always devoted to the good of all beings, who does not feel aversion for anybody, who is sweet-tongued, who is an utterer of agreeable and cooling words, who gives way to one that deserves to have way, who adores his preceptors in the manner in which preceptors deserve to be adored, who welcomes all creatures with proper courtesy, who does not hear ill will towards any creature, who lives, worshipping seniors and guests with such honours as they deserve, who is ever bent upon securing as many guests as possible, and who worships all who honour his house with their presence, succeeds, O goddess, in ascending to Heaven. Upon the exhaustion of his merit, he takes birth in the order of humanity in a high and respectable family. In that life he becomes possessed of all articles of enjoyment in abundance and jewels and gems and every kind of wealth in profusion. He gives unto deserving persons what they deserve. He becomes devoted to the observance of every duty and every act of righteousness. Honoured by all creatures and receiving their reverence, he obtains the fruits of his own acts.
