"Monks, there are these four meditators.
Which four?
Here, monks, a certain meditator is skilled in attainment regarding concentration, but not skilled in readiness regarding concentration.
Here again, monks, a certain meditator is skilled in readiness regarding concentration, but not skilled in attainment regarding concentration.
Here again, monks, a certain meditator is neither skilled in attainment regarding concentration, nor skilled in readiness regarding concentration.
Here again, monks, a certain meditator is both skilled in attainment regarding concentration and skilled in readiness regarding concentration.
There, etc.
