Lately, I have been practicing mindfulness of the body with a renewed intensity:
"Furthermore, when going forward & returning, he makes himself fully alert; when looking toward & looking away... when bending & extending his limbs... when carrying his outer cloak, his upper robe & his bowl... when eating, drinking, chewing, & savoring... when urinating & defecating... when walking, standing, sitting, falling asleep, waking up, talking, & remaining silent, he makes himself fully alert. And as he remains thus heedful, ardent, & resolute, any memories & resolves related to the household life are abandoned, and with their abandoning his mind gathers & settles inwardly, grows unified & centered. This is how a monk develops mindfulness immersed in the body."
~ Kayagatta - Sati Sutta; Thanissaro Bikkhu translation ~
And, I have noticed something arising in the process.
Thinking mind does not like that I am placing so much attention on 'simple' matters. What is the big deal with noticing each step? Left foot, right foot . . . What is the big deal with noticing each stroke during swim practice? Left arm, right arm . . . What is the big deal with noticing each sip of tea? . . . and each bite taken? . . . What is the big deal?
Thinking mind has a strong opinion about this, I noticed. If I was not careful, thinking mind would take me down another path, where thoughts about past, present and future rule.
In the heart, doubt tries to creep in.
The benefit of right view coupled with mindfulness, soon becomes clear, when wise mind intervenes, countering doubt with faith, and pernicious thoughts with other thoughts, planted before:
Sustained application counteracts skeptical doubt. When we can stay with the subject of meditation and do not become distracted, we gain confidence through the experience that, first of all, it is possible; secondly, that we are able to do it; and thirdly, that the results that accrue are exactly as the Buddha said. Until then, doubt arises again and again in the most insidious ways. Skeptical doubt is the enemy of faith and confidence, and therefore of practice; the mind can provide all sorts of ideas, doubts and excuses - "There must be an easier way," or "I'll try something different," or "I'll find a better teacher or a better monastery," or "There must be something that will really grip me." The mind is a magician: it can produce a rabbit out of any hat.
Skeptical doubt shows itself when we cannot fully immerse ourselves in our present situation. Skeptical doubt keeps us back, because we are afraid to lose control of self-importance. When we have a little personal experience of the results of the Buddha's teachings, our doubts are counteracted, yet not completely eliminated. At least we no longer feel unsure about practicing meditation. We have experienced results and we have also realized that it makes no difference where we practice, as long as we are steadfast. That, too, is important, because we can search for a perfect place, time, situation, or teacher until the end of our lives and never find any of these because skeptical doubt always intervenes.
