The Tao the can be told of
Is not the Absolute Tao;
The Names that can be given
Are not Absolute Names.
Opening words to a classic, legend has it Lao Tzu did not want to put his philosophy into writing but on leaving the city gates was harassed to do so and that is why we have the Tao Te Ching. I believe these opening words we're a reiteration of why he did not want to write it down and those who look into this work must take into account these words.
I quote this often to christian friends, not sure if they appreciate hearing words of eastern philosophies but I think there is a lot in this.
I walked away from christina circles because of being berated by people that could not appreciate that I was endeavouring to study the word of God. Today I face some who have learnt much of the christianese phrasebook but are not living new lives.
If we can apply some of these words to our faith we may not be so condescending and start actually 'listening to the spirit' when we deal with other people.
Still got a long way to go, we all do.
