The following excerpt was taken from “The Summits of God-Life: Samadhi and Siddhi” by Sri Chinmoy.
The world has seen thousands and thousands of liberated souls, but not all liberated souls work in the world of ignorance. Many are afraid that ignorance will threaten them and try to devour them. One who is just liberated has come out of the room which is full of darkness, but this does not necessarily mean he is truly qualified to be a spiritual guide. To be a spiritual guide in the highest sense of the term, one must be commissioned by the Supreme. One may have spiritual knowledge, spiritual power and so forth, but if he is not authorised by the Highest to guide humanity, he cannot be a real spiritual Master.
