Well, the first would be the Dao De Jing by Lao Zi, The Wisdom of the Way. For English speakers, I recommend the Ursula K. Le Guin translation. It's pure poetry. You can even find it on GitHub online. It teaches us how to see the flow of the Dao, of the way, and how to act with wu wei, which is effortless action. And if you are interested in this kind of binary, the raw binary of Taoism that goes even more ancient than the Tao Te Ching, then another book is the Yijing, which is not meant to be read cover to cover, but rather is the binary code that defines the Tao, that defines the interactions of the way. And many people use it as kind of a demination tool that literally just randomly pulls from it. There's many ways to navigate it like a maze.
