Kāyagatāsati — Mindfulness Immersed in the Bodyvipassana theravadaThe instruction is unglamorous and exact: when walking, know that you are walking; when standing, know that you are standing; when sitting, sitting; when lying down, lying down. From there it extends through the parts of the body and the breath. It asks for no special time and no special place — it is the plainest possible answer to the question of where attention should be. Given in the Kāyagatāsati Sutta (Majjhima Nikāya 119), which treats knowing the body as a full path rather than a preliminary.What it's for

Body Disconnect — Numbness toward your own body is read not as a broken sense but as an unused one. This tradition's answer is repetition in ordinary postures rather than intensity — knowing you are sitting, hundreds of times.

Panic — Panic is read here as attention swept into a projected future — what is about to happen, what this might be — while the body is left behind in a present that is, in fact, survivable. Returning to what is felt is returning to the only tense in which nothing has gone wrong.

Performance Anxiety — Nerves before the moment are read as attention already in the moment, rehearsing it. Bringing it into the body's current position is how this tradition takes it back from a room you are not yet standing in.
