Everytime modern life starts eating at me... I take moment to glance in one of a select few books. One is Miyamoto Musashi's "book of Five Rings", one is "Bushido, the warrior's code" by Inazo Nitobe, and the last is the Tao Te Ching.
The Tao that can be explained... is not the true Tao, so I won't try to explain it, just that is can add a deeper, although more simplistic meaning to your life.
I study, but do not pretend to understand... the book's meaning changes for every new level of knowledge you gain. The sayings possess increadable depth, and I've found a few that have changed my life, as I increase my knowledge of the martial arts... one in particular comes to mind.
"If a violent man... does not come to a violent end. I choose him to teach me." -Lao Tzu.
I'd suggest obtaining a copy of this book, it can only help you...
