“One guru will not suit everybody. All minds are different. There are three minds: the gunas—sattwa, rajas, and tamas. A person who by habit is a guru shall cater to all these three gunas at the level of that guna. A guru will come to the level required and still be a guru. A guru is the most flexible man. He must cater at every level because he is a channel through which wisdom flows; therefore, his channel must fit in everywhere.” Yogi Bhajan
