The concept of "the Way" shows up in different but overlapping concepts in various spiritual teachings. How you find your way, what way you follow, how you navigate through life, even what Star in Tarot you follow is all in some sense an important part of who you are and, certainly, how you live your life.
The Tao is "the flow of the Universe". But it is also "the flow" in any individual aspect or part of the Universe. It is also used to mean path or teaching. Sometimes it is likened to the grain running through wood. Dharma also includes the collective concept of Nature and what it teaches, as well as the path or teaching that you follow. Each individual should ultimately find and follow his own Dharma. Jesus in the Bible uttered these now rather misunderstood words: "I am at the Way, the Truth and the Light. No man cometh unto the Father but by me". He also told his disciples that they were not dependent on having him stick around because they could find the power of the Holy Spirit within themselves.
