Are You Drowsy?

Then the Lord to Mahā Moggallana: “Are you drowsy, Moggallana? Are you drowsy?”

“Yes, Lord.” “Well, then, whenever the thought of laziness befalls you, pay no attention to that thought, do not dwell on it. Doing this, it is possible that it will pass.

But if, by so doing, that laziness does not pass, then you should think and reflect in your mind about the Dhamma – review it in your mind as you have heard it and learned it. Doing this, it is possible that the laziness will pass. But if, by so doing, the laziness does not pass, then you should recite the Dhamma in detail as you heard it and learned it. Doing this, it is possible that the laziness will pass.
