Araka’s Instructions
Arakenānusasani Sutta  (AN 7:70)

“Once, monks, there was a teacher named Araka, a sectarian leader who was free of passion for sensuality. He had many hundreds of students and he taught them the Dhamma in this way: ‘Next to nothing, brahmans, is the life of human beings—limited, trifling, of much stress & many despairs. One should touch this (truth) like a sage, do what is skillful, follow the holy life. For one who is born there is no freedom from death.

…

“‘Just as a river flowing down from the mountains, going far, its current swift, carrying everything with it, so that there is not a moment, an instant, a second where it stands still, but instead it goes & rushes & flows, in the same way, brahmans, the life of human beings is like a river flowing down from the mountains—limited, trifling, of much stress & many despairs. One should touch this (truth) like a sage, do what is skillful, follow the holy life. For one who is born there is no freedom from death.
