This book is a quick primer on the shamatha meditation style written by a practitioner and published by an organization following the Shambhala school of Buddhism. That said, the book is heavy on the practice of meditation and thin on the philosophical tenets of Buddhism.
The early parts of the book contrast shamatha with other types of meditation and gives a quick overview of some of the schools of Buddhism, but the real focus of the book is encouraging the practice of meditation, particularly shamatha-style, which involves focusing on the breathing.
Buddhist thought aside, the book provides good insight into methods to still yourself each day. Which I’ll try to focus more on. But the author insists I should follow the millenia-old teachings of actual Buddhist masters instead of breathing according to the Relax setting on my watch. I don’t plan to set up a meditation space in my home nor conduct a meditation retreat weekend with all natural foods and lots of napping (well, I might plan lots of napping), but I’ll try sitting in better posture and focusing on my breath while trying to relax.
So it was an interesting and informative book to read, written for a quick read and, perhaps, for future reference if you become a meditator.
