Any form of knowledge that regards itself as the truth, and not simply an analogy to it, is most certainly a lie.
A path is only a path, and there is no affront, to oneself or to others, in dropping it if that is what your heart tells you … Look at every path closely and deliberately. Try it as many times as you think necessary. Then ask yourself alone, one question … Does this path have a heart? If it does, the path is good; if it doesn’t it is of no use.
— Don Juan, [transcribed by Carlos Castaneda]
