Mindfulness

Mindfulness is sati, from a root that also means “remembering”. On the cushion, the instruction is simple: notice what arises and let it go. Off the cushion it isn’t that simple, because some of what you notice should be acted on, written down or remembered.

The two poles

Letting it pass Marking it

Both are honest. Neither is the right answer.

The Tension

A flash of irritation in a meeting. A small kindness from a stranger. A thought that keeps coming back, about your health, a relationship, or the job.

Letting it pass means noticing without grabbing hold, so the feeling or thought moves through without becoming a story. Marking it means deliberately registering it: naming it, remembering it, treating it as information that matters.

Letting it pass can be equanimity, or it can be a way of not looking. Marking it can be insight, or it can feed rumination.

What the Tradition Says

In the Dvedhāvitakka Sutta (MN 19), the Buddha describes his own practice before awakening. He sorted thoughts into two kinds: those that led toward harm and those that didn’t. He didn’t let everything pass. He marked each thought, saw where it led, and let that decide what came next.

The Vitakkasaṇṭhāna Sutta (MN 20) goes the other way. For some unwholesome thoughts, one remedy is simply not to attend to them and let them fade from lack of attention.

So the tradition keeps both tools. Mindfulness is knowing which one the moment needs.

How It Shows Up in the Practice

Each day includes one Mindfulness item: a check-in on what you noticed, a question about what you did with it, or a situation where you choose whether you would let it pass or mark it. Patterns shows your lean between the two poles over time, and how often what you were watching for actually came up.

A Practice for Today

The next time something catches your attention, whether irritation, delight or a nagging thought, give it one breath. Then decide on purpose: let it pass, or mark it. If you mark it, write one line. If you let it pass, notice whether it comes back.
