For example, Nath yogi sadhus have been viewed with a certain degree of suspicion particularly amongst the urban populations of India, but they have been revered and are popular in rural India. However, reverence of sadhus is by no means universal in India. Thus seen as benefiting society, sadhus are supported by donations from many people. It is also thought that the austere practices of the sadhus help to burn off their karma and that of the community at large. Sadhus are widely respected for their holiness. According to various assumptions, there are 4 to 5 million sadhus in India today.

So, it is very difficult to determine the exact number of Sadhus. Unlike skilled and professionals, there is no certification for Sadhus. It literally means one who practises a ″sadhana″ or a path of spiritual discipline. The same root is used in the word sādhanā, which means "spiritual practice". The words come from the root sādh, which means "reach one's goal", "make straight", or "gain power over". 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. In the Hindu Epics, the term implies someone who is a "saint, sage, seer, holy man, virtuous, chaste, honest or right". In the Brahmanas layer of Vedic literature, the term connotes someone who is "well disposed, kind, willing, effective or efficient, peaceful, secure, good, virtuous, honourable, righteous, noble" depending on the context. The term sadhu (Sanskrit: साधु) appears in Rigveda and Atharvaveda where it means "straight, right, leading straight to goal", according to Monier Monier-Williams.
