After the sitting & walking meditation, we read and discussed an article by Chogyam Trungpa titled, Put Your Meditation into Action. Here's an excerpt:

One purpose of meditation is to develop a feeling of stillness and solidity in one’s practice. In order to become more open, one needs to establish the ground from which one will open. From the simplicity of mindfulness we begin to develop clear seeing, and we begin to make a transition to insight meditation. We are attempting to prepare ourselves for a path that is dedicated to working with other people as well as ourselves.
