There are these phrases you come across in the sutra’s, “the holy life has been lived” for example. If you read more widely you will see that in ancient India around the time of the Buddha it was a thing, that certain people would renounce, and would become wandering sannyasi. Mention of this goes back in the Veda’s to the second millennium BCE.
Saṃnyāsa in Sanskrit nyasa means purification, sannyasa means "Purification of Everything". It is a composite word of saṃ- which means "together, all", ni- which means "down" and āsa from the root as, meaning "to throw" or "to put". A literal translation of Sannyāsa is thus "to put down everything, all of it".
It is something that has somewhat gone out of fashion, in todays materialistic society very few people choose to give up work, to lay down all burdens. But those people who study the Buddha’s words and would learn from him do follow in the footsteps of those ancient renunciates.
So maybe it is a good idea to see what we can lay down today? Living a life of voluntary simplicity is perhaps as close as we can come to living the holy life as they did in the time of the Buddha.
