The fourth and final Foundation of Mindfulness is of phenomena. You might be asking yourself right now, ‘But aren’t the body, the feelings and mental activity phenomena too?’ and you would be right. This is an indicator of the way that the Four Foundations of Mindfulness function as progressive steps of integration of awareness within the totality of our individual experience. The idea that these Four Foundations exist separately is false. They are simply steps or stages of working with specific aspects of our experience. As with the previous three Foundations, Mindfulness of phenomena includes not only a resultant and integrative dimension, but also an active, volitional path of techniques and material to work through and integrate. And the key term is integration: when we have full awareness of the body, we have awareness of feeling and phenomena and the quality of mental states too. We break down perception into specific perceptual frames first, and then we build up an integrated perceptual outlook that is inclusive and cognisant of the interdependent nature of all phenomena within our field of perception. We work through the foundations individually because our experience of each of them is polluted by conditioning, patterned and therefore partial living, and our gross and subtle conceptualisation of experience.
