Jon Kabat-Zinn has his own, and famous, definition of mindfulness:
“Mindfulness means paying attention in a particular way;
in the present moment, and
And I have always found that definition both good and precise. Trouble is the phrase “present moment”, because we ca fundamentally never be in the present moment. We can only hunt for it, because when we come close, it is already gone. Even “here and now” is not precise, although a bit closer to the truth.
The definition on wildmind.org is more true to the fundamental charecteristics of mindfulness:
Mindfulness is the gentle effort to be continuously present with experience.
But this last definition miss the essential point in the definition of Jon Kabat-Zinn, the word “nonjudgmentally”. To be real mindful one has to be aware without judgment of any kind.
So I ended up with my own definition, which is more to my understanding:
Mindfulness is unconditional awareness of what is
Everything just “is”. Nothing more, nothing less. So easy, yet so difficult.
