"Just as a firebrand from a funeral pyre -- burning at both ends, covered with excrement in the middle -- is used as fuel neither in a village nor in the wilderness: I tell you that this is a simile for the individual who practices neither for his/her own benefit nor for that of others. The individual who practices for the benefit of others but not for his/her own is the higher & more refined of these two. The individual who practices for his/her own benefit but not for that of others is the highest & most refined of these three. The individual who practices for his/her own benefit and for that of others is, of these four, the foremost, the chief, the most outstanding, the highest, & supreme. Just as from a cow comes milk; from milk, curds; from curds, butter; from butter, ghee; from ghee, the skimmings of ghee; and of these, the skimmings of ghee are reckoned the foremost -- in the same way, of these four, the individual who practices for his/her own benefit and for that of other is the foremost, the chief, the most outstanding, the highest, & supreme.

"These are the four types of individuals to be found existing in the world."
