The Tao Te Ching can be considered as the core book to Taoism. It’s the most translated book in human history. You can find hundreds of variations of the Tao Te Ching. No one translation is truly better than another. Each one will teach a different angle to Taoism.
It is spiritual poetry. Westerners get confused by the Tao Te Ching since they try to force a meaning to each chapter. Rather relax, and let each section inspire you.
It’s good to try different versions until you find a translation that calls to you.
I have three public domain translations of Tao Te Ching on the Personal Tao site.
