No one holds up a mirror to his reader more effectively than OSHO. Pick up any of his books and read one page, and you will forget you are reading, and will realize that you are observing your own life, and your own character. If Krishnamurti is right, that to deeply observe oneself is to solve one's conflicts, than OSHO brings me closer to this than any other author. But that is not all: his writing brims with love and honesty. And in this book he is approaching the greatest advocate for love and honesty that the world has seen: Jesus. It is typical that OSHO studied Jesus; he considered him one the most important enlightened persons in history. He has no need to deify him, just as he does not need to deify anyone. That is not the point for OSHO; the point is, rather, for the person to achieve wholeness, peace, and love. He knows that Jesus is a master who can bring those things to you. He is without peer in having no apparent prejudices whatsoever, in favor of any established institution. He is all about the individual, living in the world. His books have had a major positive impact on my life. The only limitation on this impact is my own fear of or reluctance to change. But these books are beautifully written, and will challenge you to move beyond stereotypes, to become who you should be. And The Mustard Seed is absolutely my favorite book of his. I feel I should address a point brought up by another reviewer, who was very angry about the "anti-semitic" comments, in which OSHO suggests that the Nazis were a punisher that appeared for the Jewish people. It is true that OSHO sometimes strayed a little too far in his analysis. He occasionally is a bit out there, such as in one of his books when he suggests that the trees become scared if you walk into the woods with an axe. But it is important to note that he was not uttering anti-Semitic statements per se; he does not hate Jewish people. Rather, he was attempting to describe (albeit in a very unfortunate manner) the universal nature of the law, that if one sins, somehow one ends up being punished for it. These occasional excesses should not be seen as diminshing his work. These books are transcripts of extemporaneous talks he gave; anyone, talking for hours on end will say a goofy thing here and there. Take my word for it, though, read his books with an open mind, and you will feel your mind opening up and your world expanding. This is not b.s. new-agey stuff; it is the essence of great spiritual writing.
