+Traditionally, many subtle distinctions are made about the various
+characteristics and levels of the development of bodhichitta. Chagme Rinpoche
+mentions these and says, “If you are studying to become a scholar, you need
+to know all of these distinctions. But if you are a practitioner, these
+distinctions are extremely unimportant.” For example, I arrived here at
+these teachings by traveling in airplanes and automobiles. Now, I might
+wonder, “Who built the airplane I traveled in? How does it work?” But, in
+fact, I don’t know the answers to any of these things because it is not
+important for me to know these things. What is important is that I got on an
+airplane and flew thousands of miles and was able to get here. In the same
+way, I regularly travel by automobile, and I might wonder, “How do you make
+an automobile? Who made this automobile? How does it work exactly?” From
+one point of view, of course, it is good to know these things, but from the
+point of view of actually getting somewhere, it is not important. What is
+important is that I got in a car and I came here. So, from one point of view,
+it might be important to know all about the various aspects and
+characteristics of bodhichitta, but according to Karma Chagme, it is perfectly
+okay if you don’t.
