Therefore they call even now a man who does not give alms here, who has no faith, and offers no sacrifices, an Âsura, for this is the doctrine (upanishad) of the Asuras. They deck out the body of the dead with perfumes, flowers, and fine raiment by way of ornament, and think they will thus conquer that world.

In plain words: That is why people still call someone who gives no charity, has no faith, and makes no offerings a demon-like person, because this is the demons' teaching. Such people decorate dead bodies with perfume, flowers and fine clothes, thinking this will win them the next world.
