The Sanskrit terms sādhu ("good man") and sādhvī ("good woman") refer to renouncers who have chosen to live lives apart from or on the edges of society to focus on their own spiritual practices.[2]
The words come from the root sādh, which means "reach one's goal", "make straight", or "gain power over".[3] The same root is used in the word sādhanā, which means "spiritual practice".
