We've never done this kind of meditation before, so this will be a learning experience. It's recommended by the Dalai Lama in his new book, Beyond Religion, which, for a religious leader, presents a laudably secular vision.
In this meditation, one begins by gazing at visual object. Then, one attempts to hold a mental image of the object in the mind's eye. It's a form of concentration meditation.
If you can, please bring a small object to gaze upon. I'll bring some seashells.
