The talk describes both, Buddhist teachings on everyday's action (body, speech and mind) and teachings about meditation, with strong emphasis on anatta and equanimity.
The Buddha instructed us to see events as "not me, not mine, not who I am." When the body, choices, personal history and the narrator are seen in this way, the happiness of peace becomes possible.
The natural expression of emptiness or anatta is compassion or friendliness. This motivation of heart develops naturally as wisdom and mindfulness deepen and we cannotice this happening both in retreat and in our daily lives.
