I would like to point out that logically this quote can be reduced to:
1. Take no action
2. Take no abusive action
3. Take no abusive action to interfere
4. Take no abusive action to interfere with the course of Nature.
For without any action non of the other can take place.
I know I'm a Taoist because I can see what is being pointed at with the words, rather then take the words too seriously or stare at the finger that is pointing. Being a Taoist is something to realize and experience, not something to understand or know. I think even by calling yourself a Taoist you are taking on a label of whatever you think is a Taoist, but even that is not what you really are because it is dependent upon what you think is a Taoist.
