True knowledge is a virtue of the talented, but harmful to those without discernment. Spring water free of impurity, entering the ocean, becomes undrinkable.
Great compassion penetrates into the marrow of the bone. It is the support of all living beings. Like the love of a parent for an only child, the tenderness of the Compassionate One is all-pervasive.
Just as the grammarian makes one study grammar,
A Buddha teaches according to the tolerance of his students;
Some he urges to refrain from sins, others to do good,
Some to rely on dualism, other on non-dualism;
And to some he teaches the profound,
The terrifying, the practice of enlightenment,
Whose essence is emptiness that is compassion
He who does not attempt to make peace / When small discords arise, / Is like the bee's hive which leaks drops of honey / Soon, the whole hive collapses.
That which arises dependent on something is not in the least that thing, neither is it different from it. Therefore, it is neither permanent or nothing.
The Buddha taught some people the teachings of duality that help them avoid sin and acquire spiritual merit. To others he taught non-duality, that some find profoundly frightening.
Ultimate serenity is the coming to rest of all ways of taking things, the repose of named things; no truth has been taught by a Buddha for anyone, anywhere.
