[96] Bhikkhus, these four persons are found existing in the world. What four? One who practices for his own welfare but not for the welfare of others; one who practices for the welfare of others but not for his own welfare; one who practices neither for his own welfare nor for the welfare of others; and one who practices both for his own welfare and for the welfare of others.
And how, bhikkhus, is a person one who practices for his own welfare but not for the welfare of others? Here, bhikkhus, a certain person practices for the removal of lust (rāga) in himself but does not encourage another in the removal of lust; he practices for the removal of hatred (dosa) in himself but does not encourage another in the removal of hatred; he practices for the removal of delusion (moha) in himself but does not encourage another in the removal of delusion. It is in this way, bhikkhus, that a person is one who practices for his own welfare but not for the welfare of others.

And how, bhikkhus, is a person one who practices neither for his own welfare nor for the welfare of others? Here, bhikkhus, a certain person does not practice for the removal of lust in himself, nor does he encourage another in the removal of lust; he does not practice for the removal of hatred in himself, nor does he encourage another in the removal of hatred; he does not practice for the removal of delusion in himself, nor does he encourage another in the removal of delusion. It is in this way, bhikkhus, that a person is one who practices neither for his own welfare nor for the welfare of others.
And how, bhikkhus, is a person one who practices both for his own welfare and for the welfare of others? Here, bhikkhus, a certain person practices for the removal of lust in himself and also encourages another in the removal of lust; he practices for the removal of hatred in himself and also encourages another in the removal of hatred; he practices for the removal of delusion in himself and also encourages another in the removal of delusion. It is in this way, bhikkhus, that a person is one who practices both for his own welfare and for the welfare of others.
These, bhikkhus, are the four persons found existing in the world.
