When I discovered the Kabir Book, it was like a breath of fresh air. Is this a spiritual book? Sure, yes. But it is also hilariously funny and entertaining, if you ask me.
Finding Kabir was great. This ancient sage skewers all kinds of religious dogmas and funky practices. It is comforting to know that he pursued his path and still snickered at stern, narcissistic people who shaved their heads and wore uncomfortable burlap. Kabir's sarcasm and satire is especially timely in light of recent corrupted interpretations of yoga, Buddhism, Sufism and other spiritual/religious approaches.
In essense, Kabir offers something of a "Newage Treatment Plant." If you like metaphysics without a bunch of gunk polluting it, then Kabir is for you.
I have one concern. Robert Bly states that he has changed the wording and content of poems to make them understandable to a contemporary audience. I've heard that much is lost and possibly even corrupted with such a translation. I'm not sure where Kabir ends and Bly begins.
