The incessant untrained mind
Is like a dripping faucet with an open drain;
Never full of contentment, never empty of thought.

The stable training mind
Is like a dripping faucet with a closed drain;
On the way to fullness, every drop of mindful practice adds up.

The overflowing master's mind
Is like an overflowing tub with a constant faucet and closed drain.
Full of bliss, he stands as a totem of overflowing wisdom and insight.
