Mindfulness and clear consciousness
"As soon, brahman, as a monk is intent on vigilance, the Tathagata disciplines him further, saying: 'Come you, monk, be possessed of mindfulness and clear consciousness, acting with clear consciousness whether you are approaching or departing, acting with clear consciousness whether you are looking ahead or looking round, acting with clear consciousness whether you are bending in or stretching out [the arms], acting with clear consciousness whether you are carrying the outer cloak, the bowl or robe, acting with clear consciousness whether you are eating, drinking, munching, savoring, acting with clear consciousness whether you are obeying the calls of nature, acting with clear consciousness whether you are walking, standing, sitting, asleep, awake, talking or being silent.'
