In Buddhist scriptures there is recorded a story that goes like this: a prestigious monk knew that his little novice monk just had only 7 days left in his life, he let the novice monk go back home to visit his family. On his way home, it was raining very hard, the little novice monk discovered a group of ants trying really hard to climb up out of the pool zone, yet they were flushed away again and again by the water. The little novice monk felt sympathy for them and saved all the ants one after another. 7 days later, the little novice monk came back to the monastery, the master surprisingly discovered that his disease had improved much. Later the master found out that the little novice monk’s bowel of mercy had not only saved the ants but also helped him live a longer life.
A little bowel of mercy could rescue the precious life which built up endless merits and virtues.
If we put accumulated dry grass into a mountain-like tall pile, just a small flame could burn all the grass. Why? Because a small flame can also burn high. This is similar to how all flesh accumulate their bowels of mercy which can definitely burn all kinds of sorrows of the body and mind.
