Kāśyapa then led his 500 disciples to the cave to put out the fire. Some of them carried water and others brought ladders, but they weren’t able to put out the fire. It was the Bhagavān’s power that did. The Bhagavān then entered the concentration of kindness and slowly made that serpent stop being hateful. The evil serpent’s mind then became fearful. It ran east and west, trying to leave the cave, but it wasn’t able to find the exit. The evil serpent then went up to the Tathāgata and coiled up in his alms bowl.
