Don’t sacrifice your own welfare
for that of another,
no matter how great.
Realizing your own true welfare,
be intent on just that.
-Dhammapada [166]

All tremble when there is a weapon,
Everyone fears death;
Feeling for others as for oneself,
One should neither kill nor cause to kill.
-Dhammapada

A student asked: “For all the different people who have come to listen to your words, please tell us about the way you have found and known.”

The Buddha answered: “When you take things it is because of a thirst, a clinging, and a grasping. You should lose that and lose it altogether, above, below, around, and within. It makes no difference what it is you are grasping. When you grasp, you are losing your freedom. Realize this and grasp at nothing. Then you will cease being a creature of attachment, tied to the powers of death.”
-Sutta Nipata

A name is imposed on what is thought to be a thing or a state and this divides it from other things and other states. But when you pursue what lies behind the name, you find a greater and greater subtlety that has no divisions. Atoms of dust are not really atoms of dust but are merely called that. In the same way, a world is not a world but is merely called that.
-Visuddhi Magga

He knows his former lives.
He sees heavens and states of woe,
has attained the ending of birth,
is a sage who has mastered full-knowing,
his mastery totally mastered:
he’s what I call a brahmin.
-Dhammapada [423]

The non-doing of any evil,
the performance of what’s skilful,
the cleansing of one’s own mind:
this is the teaching
of the Awakened.
-Dhammapada [13]

For, living with a fool,
one grieves a long time.
Painful is communion with fools,
as with an enemy always.
Happy is communion
with the enlightened,
as with a gathering of kin.
-Dhammapada [15]

It is necessary to cultivate some discipline of mind, for an undisciplined mind always finds excuses to act selfishly and thoughtlessly. When the mind is undisciplined, the body is also undisciplined, and so is speech and action.
-Anguttara Nikaya

From the time there appears in this world one who has seen the truth, a fully awakened one, blessed by the truth, abounding in happiness, a teacher of wisdom and goodness, a Buddha. He, by himself, thoroughly knows and sees this universe, and knowing it, makes his knowledge known to others. The truth, lovely in its origin, lovely in its progress, lovely in its consummation, he proclaims. A new life he makes known, in all its fullness.
