Lovingkindness by Sharon Salzberg
Lovingkindness is a buddhist book focused on dealing with other people. It offers wisdom and meditation exercises on forgiveness, gratitude, compassion, and sympathetic joy. The goal is to feel more connected to others and more open and tolerent in your daily life. The writing was straightforward and the lessons were useful. The book was practical and not overly spiritual in terms of karma or reincarnation.
Lovingkindness is an excellent philosophy to practice and I hope to practice it more regularly thanks to this book.
