This book is on the traditional practice of mind traing

In Tibetan, lo means “mind” and jong means “training,” and this training is regarded as the most important single teaching in Buddhism. Based on developing a deep compassion for ourselves and for other beings, it gives us a simple method of learning to be less self-centered and selfish. The paradox is that our compassion eases the distress we find around us and also heals our own unhappiness. The deeper our concern for other people’s suffering and the stronger our wish to help them, the less we suffer ourselves.
