attempts by researchers to develop with some degree of valid-
ity and precision various scales to “measure” mindfulness [see Chapters by
Brown and Cordon; and Baer, Walsh and Lykins]. Along with these attempts
come many attendant problems that are also well-recognized in these pages
and elsewhere [6].
The choice to have the word mindfulness does double-duty as a com-
prehensive but tacit umbrella term that included other essential aspects of
dharma, was made as a potential skillful means to facilitate introducing what

Nyanaponika Thera referred to as the heart of Buddhist meditation into the
mainstream of medicine and more broadly, health care and the wider society
in a wholly universal rather than Buddhist formulation and vocabulary. I felt
that Nyanaponika Thera’s inclusive and non-dual formulation offered both
validation and permission to trust and act on my own direct experience of
the meditation practice and the dharma teachings I had received over the
course of my life, even if technically speaking, it was glossing over impor-
tant elements of Buddhist psychology (as outlined in the Abbidharma, and
in Zen and Vajrayana teachings) that I felt could be differentiated and clari-
fied later, once it was recognized that mindfulness , based on our operational
definition, however, it was construed or contextualized in detail, might con-
tribute profoundly to clinical care and to our understanding of the nature
of the mind itself in a Western mainstream medical and scientific setting. In
Nyanaponka’s words, mindfulness is
the unfailing master key for knowing the mind and is thus the starting point;
the perfect tool for shaping the mind, and is the focal point; and the lofty
manifestation of the achieved freedom of the mind, and is thus the culminating
point.[7]
That means that mindfulness is the aim, the methods or practices, and the
outcome or consequences all wrapped up together, wholly fitting for a non-
dual orientation that emphasizes nowhere to go, nothing to do, and nothing
to attain [8]. Together with the words of the Buddha in his most explicit
teaching on mindfulness, found in the Mahasattipathana Sutra, or great sutra
on mindfulness
this is the direct path for the purification of beings,
for the surmounting of sorrow and lamentation,
for the disappearance of pain and grief,
for the attainment of the true way,
for the realization of liberation –
namely, the four foundations of mindfulness
it seemed like an appropriate choice to feature mindfulness as the uni-
fying factor and name under whose umbrella the work of the stress reduc-
tion clinic, later known as mindfulness-based stress reduction , or MBSR,
could unfold. Now we have our first clinical handbook of mindfulness, which
includes a broad range of perspectives on this veritable koan, the nature of
mindfulness, its myriad applications, and potential impacts.
To make matters even more interesting, since in all Asian languages the
word for mind and the word for heart are the same word, it feels important
to remind ourselves that unless we hear “heartfulness” when we are using
or hearing “mindfulness,” we may be missing the mark in a fundamental way
that could have unfortunate consequences both for how mindfulness-based
interventions are constructed and delivered, and for how we approach rele-
vant research issues. Many of the authors here are very strong on this point
in the discussion of their work. For me, the dimension of heartfulness re-
inforces the core Hippocratic injunction: primum non nocere – first, do no
harm, to which we all need to accord continual present-moment attention in
relationship to those who come to us with untold vulnerabilities.

Foreword
One last word on the subject of mindfulness and its definitions: a small
group of meditation teachers and Buddhist scholars recently developed a col-
lective articulation/definition of mindfulness that may
