What first comes to mind to speak about is my own spiritual materialism. I find that as I'm reading or reflecting upon the teachings and something becomes clear to me, I immediately want to rush out and teach it to others. Why is this? The answer disturbs me, because although I believe there is a certain amount of good motivation, looking deeply, I discover that actually there is very little intention to help others. Instead, it's all about making an impression, and there is much of my own ego involved.
This is an incredibly important lesson all of us who are on the path of progressive and incremental enlightenment must learn.
