Enlightenment's Correct Job
Attaining my true self simply means moment to moment I keep a correct situation, correct relationship, and correct function in this world. I function clearly in this universe to save all beings.
So getting enlightenment and teaching other beings are not two things, because when you return to your mind before thinking arises, at that point, everything completely becomes one. At that point, how could you not help all beings? Your correct situation, correct relationship, and correct function appear clearly in front of you. Helping other beings is enlightenment's correct job - it is really not all that special. This is the true purpose of Buddhism.
