Question: Can you explain the difference between Yogis, Rishis and sadhus?

Babaji:

A Yogi can be said to be the state that is the highest. A Yogi is in total re-union with God. A sadhu or saint is simply a mild, peaceful person who thinks of God. The terms 'Rishi’' or 'Maharishi’' are used depending on the tapas performed. 'Paramahamsa’ is the same as 'Yogi.'

In the Yoga Vasistha, it is said that once a person has become a Yogi, then they are equal to God. They can even be worshipped by others. Such a person sees one single Self everywhere.
