During this talk, Peter described lovingkindness as an expression of the Wisdom aggregate of the Noble Eightfold Path, that is, Right Intention (which he renames Benevolent Intention). The four Divine Abidings were described: lovingkindness, compassion, empathetic joy/generosity and equanimity. The first three focus on overcoming greed and hatred, and the fourth, equanimity, aligns with insight practice (vipassana) to investigate and bring balance to the first three. Peter also read a translation of the Metta Sutta, then placed emphasis on current psychological research the indicates that the degree of kindness that a mother manifests towards her child brings great benefit to the development of a healthy personality structure. This was accompanied by an explanation of the psychological and neurological impact of sincere silent repetition of a metta mantra.
At the end of his explanations, he read an excerpt from an editorial article by the Dalai Lama published in the New York Times recently advocating the benefits of compassionate action in the midst of current cultural and environmental turmoil. This was followed by general discussion among those attending on the benefits of lovingkindness practice.
Here are the notes prepared for this talk, including the Metta Sutta, the metta mantra, and the NYT excerpt by the Dalai Lama.
