The Discourse on Concentration as Root and Acting Carefully
669.
At Sāvatthī.
"Monks, there are these four meditators.
Which four?
Here, monks, a certain meditator is skilled in concentration regarding concentration, but not one who acts carefully regarding concentration.
Here again, monks, a certain meditator is one who acts carefully regarding concentration, but not skilled in concentration regarding concentration.
Here again, monks, a certain meditator is neither skilled in concentration regarding concentration, nor one who acts carefully regarding concentration.
Here again, monks, a certain meditator is both skilled in concentration regarding concentration and one who acts carefully regarding concentration.
Therein, monks, the meditator who is both skilled in concentration regarding concentration and one who acts carefully regarding concentration is the foremost and the best and the chief and the highest and the most excellent among these four meditators.
Just as, monks, from a cow comes milk, etc.
and the most excellent."
