This link will take you to an still active site having a number of translated to English versions of the Tao Te Ching
I posted several translated versions of the Tao Te Ching in the library. Each version will have cross links so a reader can quickly jump and compare the various translations. No one version is correct. Instead focus on the images you experience while reading each one.
Keep in mind hundreds of other translations exist.
What’s an acceptable translation? Scholars fight entire careers over this little topic.
So to clear things up, here is the truth of the matter:
Taoism simply states: it doesn’t matter. Words can never capture the true Tao.
Translations change over time, due to personal differences, cultural changes and the shifting nature of language to be relative to now. So discover over time new meanings upon each reading. This is about your own relative needs “in the now” determining how to best embrace these works.
Don’t worry about the translation… just enjoy each one as it is!
