Budhha's teaching of the full awareness of breathing is contained in his Anapanasati Sutta. It consists of sixteen breathing awareness exercise. A mere reading of their wording may prove to be futile as they are meant for practical learning from experience; you experience them as you perform them and carefully like you do by performing an experiment in a science laboratory. In the case of these exercises, the laboaratory is the learner him/herself. The learner goes through these exercises with full attention and becomes aware of their effects on her/his body-mind.
First two groups of exercises are related with developing mindfulness and understanding of the body, feelings and emotions. Emotions result from the pleasant or unpleasant sensations arising from the body. Sensations result in feelings which strengthen into enmotions which primarily control human behavior. Mindfulness and understanding of the body leads to physical health and of the emotions lead to mental health and wellness. Therefore, the first two groups are especially relevant to the SHEN Centre for Health and Wellness.
The last two groups of exercises lead to mindfulness and understanding of the mind and the objects of the mind. These goals transcend health and wellness and are especially relevant to the SHEN Centre for Meditative Sciences.
