From That the True Dhamma Might Last a Long Time: Readings Selected by King Asoka, translated by Thanissaro Bhikkhu.

And what is bodily sagacity? There is the case where a monk abstains from taking life, abstains from theft, abstains from unchastity. This is called bodily sagacity.

And what is verbal sagacity? There is the case where a monk abstains from lying, abstains from divisive tale-bearing, abstains from harsh language, abstains from idle chatter. This is called verbal sagacity.

And what is mental sagacity? There is the case where a monk who -- with the wasting away of the mental fermentations -- remains in the fermentation-free awareness-release and discernment-release, having known and made them manifest for himself right in the here and now. This is called mental sagacity.

These, monks, are the three forms of sagacity.

A sage in body, a sage in speech,
    A sage in mind, without fermentation:
a sage consummate in sagacity
    is said to have abandoned
        everything.         -- the All.
