We start with a story and poem related to developing metta. Then there is an overview of the nature of metta and metta practice, and how the intention to manifest metta—good will, care, and a powerful friendliness—has many resonances with the core intentions of other spiritual traditions, often expressed in terms of manifesting love. We explore how we train in developing the intention to manifest metta and how we see what gets in the way. We look at several of the challenges of metta practice and how to work with them.
