You really can't follow a guru. You can't ask somebody to give The Reason, but you can find one for yourself; you decide what the meaning of your life is to be. People talk about the meaning of life; there is no meaning of life--there are lots of meanings of different lives, and you must decide what you want your own to be.
Often, people get a temporary high, a fleeting sense of belonging and well-being from the illusion of strength that comes from attaching themselves to gurus, without realizing that the energy they associate with the so called holy person comes from within themselves.
