I used to wonder why Master had to travel so much, because if his teaching was what elevated us, all that we had to do was to print books and send them all over the world. And if it was the practice that was to elevate us, then the preceptors were enough. They can teach us the practice. But it is the Master who is the most important, in fact, most vitally important element of this teaching. To make us understand this, Master had to travel again and again, be present with us, show Himself to us and suffer for us.
