Now, some bank up (the sepulchral mound) after covering up (the site). The gods and the Asuras, both of them sprung from Pragâpati, were contending for (the possession of) this (terrestrial) world. The gods drove out the Asuras, their rivals and enemies, from this world; whence those who are godly people make their sepulchres so as not to be separate (from the earth), whilst those (people) who are of the Asura nature, the Easterns and others, (make their sepulchral mounds) so as to be separated (from the earth), either on a basin or on some such thing.
