Pain is a great method of Prakriti (physical nature). It helps you know that you need to go to the doctor. But too much pain can just bring your system down; it can cause an internal collapse.
Pain is a great messenger, but pain by itself is not the remedy. One must listen to the messenger quickly, and in listening lies the remedy. I indeed have said that the greatest method for liberation is suffering; but why suffer so much? I haven’t said that you require unmitigated and infinite suffering to be liberated.
Wisdom lies in suffering little, and flying away quickly.
