Dhammapada Verse 159
The Story of Thera Padhanikatissa
Thera Padhanikatissa, after taking a subject of meditation from the Buddha, left for the forest with five hundred other bhikkhus. There, he told the bhikkhus to be ever mindful and diligent in their meditation practice. After thus exhorting others he himself would lie down and go to sleep. The young bhikkhus did as they were told. They practised meditation during the first watch of the night and when they were about to go to bed, Padhanikatissa would get up and tell them to go back to their practice. When they returned after meditation practice during the second and third watches also he would say the same thing to them.
