Tolle is great, he cannot lead you to enlightenment though. (Liberation is a better word, enlightenment has so many useless images and religions attached to it)
Tolle is a master of deepening the state of liberation. Reading Tolles work pre liberation is the equivalent of buying a stethoscope and hoping to transform into a doctor
I find the work don over at "Ruthless Truth" much more interesting if you are just starting out. Worked for me
You will come to tolle eventually and from a liberated perspective he makes perfect sense.
