We begin with metta as heart training, a practice of awakening and growing our heart and explore how our practice of metta can also support and help to transform others. Then we move into obstacles to metta meditation and how to practice with them, covering when metta feels mechanical, distractions, grief, doubt, anger, and struggling to offer metta to ourselves. We close looking at how metta can be a protection and also how the Earth can be a source and inspiration for metta.
