Citta is our center, but it’s conditioned to allowing itself to be occupied with transient phenomena. In meditation we can shift back to citta as the center, thereby weakening the habits of running out and trying to control circumstances.
Citta is energetic, its energies habituated to going out. Settle and calm it through the body, and sustain attention with light touch and listening, vitaka-vicara. Listen for a long time to what you place your attention on. Mind becomes calm and receptive.
Referring to various Dhammapada passages, we come to understand that citta is stuck, grasped, bound up. But it can be released with wisdom. In meditation we practice calming and steadying.
Citta can bond to body or breathing rather than running out.
The Satipatthāna Sutta is one of the most famous discourses in the Pali Canon that has informed the practice of Vipassana meditation and mindfulness meditation. The talks give an overview of the whole sutta.
