there are many other great Taoist books out there. im sure you found the concepts from the Tao Te Ching to be very confusing, well i afraid its about to be taken to a whole new level.
My personal favourite is ‘The Way of Chuang Tzu.’ he is the earliest Taoist philosopher whom there is proof of his existence – there are many theories about Lao Tzu. This book has approx 60 short stories written by Chuang Tzu and his disciple and is a beautiful read.
other excellent Taoist books are ‘I Ching’ which cover some aspects of Buddhism and Confucianism, which both have their similarities with Taoism.
Another book by Lao Tzu is ‘Hua Hu Ching’ translated as further teachings of Lao Tzu and a must read after Tao Te Ching.
There are other books which you can read but there are too many to list here, so try google-ing it.
hope ive helped 🙂
