The fundamental message of the Wu Tang music is as vast as the ocean in all reality, but it's still a straight path. You can take one lyric and by researching what that lyric is giving out to you, it should give you more than a day's worth of school, maybe three days' worth of school.
RZAIf you don't know yourself, you don't know your nature. If you don't know your nature, you don't know where to exist. By knowing your nature, knowing yourself, you know what to be and how to live. And that only comes from knowledge of self, knowing yourself.
