Nobody cannot escape from sickness. This has happened to all Supreme Buddha’s, Pacceka Buddha’s and Arahants who were endowed with great wisdom. So what could be said of us? Whenever you see anyone sick, old, you can conclude we too have suffered in the exact same way, many times in this long journey of Samsara. So my dear dhamma friends, you must put an effort to understand the suffering that we have to go through in this endless samsara.
