During a meeting on Thanksgiving Eve, Peter leads a guided contemplation describing the progression from mindfulness of breathing meditation to joy and then through gratitude to generosity.  Concentrating the mind frees up energy normally bound up by the Hindrances, and when that energy is available, the experience of joy occurs.  Joy provides the heart/mind conditions for nurturing gratitude, which leads to generosity.  This contemplation precedes a Dharma talk presented by Peter that describes the various conditioning factors of the mind that make manifest joy, gratitude and generosity.
