If you know nothing about buddhism it may be useful. It's a bit better than the wikipedia page.
Â-ձ Anapâna-sati is mindfulness on respiration. Ana means inhalation and apâna, exhalation. Concentration on the breathing process leads to one pointedness of the mind and ultimately to Insight which enables one to attain Sainthood or Arahantship. It is of no importance which posture one may adopt provided the position is easy and relaxed. The head should not be drooping. The neck should be straightened so that the nose may be in a perpendicular line with the navel. Sit with half closed eyes looking not more than a distance of three and half feet. Before the practice, bad air from the lungs should be breathed out slowly through the mouth and then the mouth should be closed.
Now inhale through the nostrils normally, without strain, without force. Mentally count one. Exhale and count two. Inhale and count three. Count up to ten constantly concentrating on the breathing process without thinking of anything else. While doing so one's mind may wander. But, one need not be discouraged. Gradually one may increase the number of series say five series of ten. Later, one may inhale and pause for a moment, concentrating merely on inhalation without counting. Exhale and pause for a moment. Thus inhale and exhale concentrating on respiration. Some prefer counting as it aids concentration while others prefer not to count.
What is essential is concentration and not counting which is secondary.
The book is divided into 11 chapters, introducing some of the core concepts in Buddhism. It starts off simple to understand but does get really deep and abstract to the end. The book is well written imo, providing a well rounded picture to the religion/philosophy and the Buddha Himself. Though a slim volume, this is not something to be finished in one sitting. Definitely a keeper to remind myself of life.
