This Sutta is closely related to the Four Noble Truths: the first Truth being that there is suffering – old age, sickness, separation, and death. But, the Buddha doesn’t stop there! He found out that, even though these inevitably exist, there is a way out of suffering them.
The Sutta is a reminder that we, as human beings, are not immune from the facts of life. If not identified with as “me” and “mine”, achieved by the various methods of contemplation, meditation, the Eightfold path, and his other recommondations, then we can take them with a pinch of salt.
It is my wish that all beings be happy and free.
Enjoy the discourse!
