"The Tao is one of the shortest books on philosopy of life ever written "

The best thing is the Tao doesnt tell you what to do. There are simply 80 or so small verses some no longer that a line or two, which could get you thinking for years. The idea however with the Tao is that you experience what they say as opposed to just intellectually understand it, which I would say is the KEY to all personal development.

Have a read of this, there is such beauty in its simplicity and truth.
