Religion?

Taoism does not require you to believe in anything.
If you look at the Tao in terms of a conventional religion, then you will be immediately confused. 
It is not about anything. It does not worship anything. It does not ask anything of you.

You are not required to preach or promote anything.
There are no special costumes. There are no holy scriptures or holy books.
See where the confusion can lie?If somebody offers to show you the Way, decline their offer.
