This book offers an original phenomenological description of mindfulness and related phenomena, such as concentration (samādhi) and the practice of insight (vipassanā). It demonstrates that phenomenological method has the power to reanimate ancient Buddhist texts, giving new life to the phenomena at which those texts point.

Beginning with descriptions of how mindfulness is encountered in everyday, pre-philosophical life, the book moves on to an analysis of how the Pali Nikāyas of Theravada Buddhism define mindfulness and the practice of cultivating it. It then offers a critique of the contemporary attempts to explain mindfulness as a kind of attention. The author argues that mindfulness is not attention, nor can it be understood as a mere modification of the attentive process. Rather, becoming mindful involves a radical shift in perspective. According to the author's account, being mindful is the feeling of being tuned-in to the open horizon, which is contrasted with Edmund Husserl's transcendental horizon. The book also elucidates the difference between the practice of cultivating mindfulness with the practice of the phenomenological epoch
