This booklet serves to provide information and instructions that will help to bring about the awakening of hearts. It includes a clear explanation of the theory and practice of metta, or loving-kindness, and how it should be applied in our daily lives, as well as when reaching out to serve others. It also explains how the practice of metta together with mindfulness leads to true freedom – freedom from all the manifestations of suffering that accompany the cycle of birth, old age, sickness and death.
