There is no gift like the gift of the Dhamma, (no acquaintance like) acquaintance with Dhamma, (no distribution like) distribution of Dhamma, and (no kinship like) kinship through Dhamma. And it consists of this: proper behavior towards servants and employees, respect for mother and father, generosity to friends, companions, relations, Brahmans and ascetics, and not killing living beings. Therefore a father, a son, a brother, a master, a friend, a companion or a neighbor should say: "This is good, this should be done." One benefits in this world and gains great merit in the next by giving the gift of the Dhamma.
