Ayaṁ vuccati, bhikkhave, pāsāṇalekhūpamo puggalo.

“Mendicants, these three individuals are found in the world. What three? An individual like a line drawn in stone, an individual like a line drawn in sand, and an individual like a line drawn in water. And who is the individual like a line drawn in stone? It’s an individual who is often angry, and their anger lingers for a long time. It’s like a line drawn in stone, which isn’t quickly worn away by wind and water, but lasts for a long time. In the same way, an individual is often angry, and their anger lingers for a long time. This is called an individual like a line drawn in stone.
