In this book, B. Alan Wallace explains a fundamental type of mental training that is designed to shift our attitudes so that our minds become pure wellsprings of joy instead of murky pools of problems, anxieties, fleeting pleasures, hopes, and frustrations. The lojong--or mind-training--teachings have been the subject of profound study, contemplation, and commentary by many great masters. Wallace shows us the way to develop our capacity for spiritual awareness through his relatable and practical commentary on the mind-training slogans.
