"Once, at a seminar, I heard a Westernized lama say that a meditator's state of mind should be like that of a hotel doorman. A doorman lets the guests in, but he doesn't follow them up to their rooms. He lets them out, but he doesn't walk into the street with them to their next appointment. He greets them all, then lets them go on about their business. Meditation is, in its initial stages, simply accustoming oneself to letting thoughts come and go without grasping at their sleeves or putting up a velvet rope to keep them out."
