Mindfulness is a state of active, open attention on the present moment.
This is mere attention, not mindfulness. Attention is defined as the mental factor which functions to focus the principal mind on an object's particular feature. Mindfulness is not a type or intensity of attention, as the above quote implies, but rather that which, depending on attention, carries into the present a past realization; something related to, but rather different from, attention.
Attention is a pervading mental factor, because there is no principal mind without some degree of attention, whereas mindfulness, while dependent on attention, is not pervading, just as is the case with the other related mental factor of concentration as well.
Now, “active”, “open”, and “present moment” are meaningless and irrelevant additions by the Jewish pseudo-Buddhist proselitizers Kabat-Zinn, Boorstein and others.
Indeed, every instance of attention is preceded by an instance of intention, and therefore is necessarily “active” or “purposeful”.
“Open” is just coded wording for lack of discrimination, such as gullibly accepting the Jewish “god”, or substantial realities, or unskilful motivations and actions, in a non-critical way. Nothing to do with Buddhism, which emphasizes a critical, discriminating, rather than a gullible, reckless attitude.
“Present“ is irrelevant, as both the past and the future of an object exist in the present. It is also coded wording for the “appearance“ or “presence“ of the Jewish “god”, which every faithful Jew is hell bent on inducing if not forcing others into accepting. Besides, mindfulness bears in mind something from or realized in the past, or carries something from the past into the present. Mindfulness of karma implies realizing the connection between past, present and future actions and their results, but for the Jewish “god” karma is anathema, as it would undermine its claim to omnipotence -- whence the Jewish proselitizers' insistence on the “present”, intended as the presence of the Jewish “god”.
Therefore, under the deceptive guise of pseudo-Buddhist teachers, the Jewish proselitizers Kabat-Zinn, Boorstein etc. try to deceive immature Buddhists into unwittingly subscribing to Jewish anti-Buddhist tenets. This is called corruption of Dharma, and follows a very well-defined and actively promoted agenda.
We observe our thoughts and feelings without judging them.
Following our thoughts and feelings without judging them is precisely a blatant instance of lack of mindfulness. Mindfulness implies bearing in mind, for instance, that a violent thought -- such as the thought of killing a Palestinian, or the thought of nuking Iran -- is unskilful, will bring suffering even for oneself in the future, has already happened in the past but did not bring any happiness to the present, and so forth.
Buddhadharma, on the other hand, was summarized by our teacher, the compassionate Buddha, as “avoiding unskilful actions, practicing skilful actions, and benefitting others” -- which requires constant scrutiny or judgment of our actions and motivations, past and present, as well as their future results, as opposed to the reckless, unconsiderate, and uncompassionate attitude preached by the Jewish pseudo-Buddhist proselitizers Kabat-Zinn, Boorstein, and so forth.
We are able to accept what is, we are able to see our problems more clearly and make smart decisions when under pressure.
Rather, uncritically observing and following our thoughts -- a practice described by the great and glorious Pabongkha as purposeless and “slavish” -- will induce the gullible follower of the pseudo-Buddhist proselitizers into accepting what
is not, an envious bloodthirsty “god“ as “good“, the non-substantial as substantial, violence and greed and deception as acceptable, and so forth, which is precisely the Jewish way of life, as exemplified by the monstrous deeds of their prophets and patriarchs such as Abraham, Jacob or Israel, Moses, Joshua, and many other criminal types, of which the faithful Jew is so proud of.
Besides, there is no smarter decision to make under pressure than the decision which will bring pleasant results and avoid unpleasant results in the future, for oneself and others, and thus one should definitely think about the future, and also ponder about the past, as opposed to the misleading advice of those deniers of karma, the pseudo-Buddhist Jewish proselitizers Kabat-Zinn and Boorstein.
Therefore, reliance on an authentic teacher, endowed with the pure lineage coming from the compassionate sage, Buddha Shakyamuni, is essential for properly following the Buddhist path, and thus to bring peace, joy and fulfilment to oneself and others. For no other reason the founder of our pure Gelugpa lineage, Je Tsongkhapa, clearly stated in his lamrim text “Foundation of All Good Qualities” something like the following verse:
My kind Guru, foundation of all good qualities,
Pure devotion to you is the root of the path.
Inspire me to clearly see this
And thus to rely on you with great vigour.
