The virtuous acts are the antithesis of the non-virtuous acts. They are extensions of observing the Precepts. They do not supplant or supersede them.
We cannot begin to protect life if we do not stop taking life.
We cannot be generous while taking what is not freely given.
We cannot speak beneficially while lying.
We cannot respect others while abusing their bodies.
We cannot cultivate sobriety while intoxicated.
How many persons who claim to be “pro-life” support the death penalty? How many eat animals every day? How many hunt? How many applaud wars?
One cannot claim to be pro-life (protecting life) and continue to directly and indirectly deprive others of life. And it is thus with all virtuous acts.
If we do not observe the Precepts, all so-called good acts are a façade, a deception.
