Strength

“Bhikkhus, a bhikkhu who has six qualities can’t attain strength in samādhi. What six? It’s when a bhikkhu is not skilled in entering samādhi, skilled in remaining in samādhi, or skilled in emerging from samādhi. And they don’t practice carefully and persistently, and they don’t do what’s suitable. A bhikkhu who has these six qualities can’t attain strength in samādhi.
