[26] **Therefore a person should always be mindful**: "Therefore" (tasmā) means: for that reason, on that account, from that cause, owing to that condition, with that as its source — seeing this danger (ādīnava) in sensual pleasures; hence "therefore." "A person" (jantu) means: a being (satta), a man (nara), a youth (mānava), a male (posa), an individual (puggala), a living being (jīva), one who is born (jātu), a creature (jantu), a mortal (indagū), a human (manuja). "Always" (sadā) means: always, at all times, for all time, constantly, perpetually, continuously, uninterruptedly, without break, in unbroken succession, arisen like ripples upon water, without interval, in continuity, cohesively, in immediate contact; before the meal and after the meal; in the first watch, the middle watch, and the last watch of the night; in the dark fortnight and the bright fortnight; in the rainy season, the winter, and the summer; in the first stage of life, the middle stage of life, and the last stage of life. "Mindful" (sato) means: one is mindful (sati) by four means: developing the establishment of mindfulness (satipaṭṭhāna) of contemplating the body in the body, one is mindful; regarding feelings (vedanā)… regarding the mind (citta)… developing the establishment of mindfulness of contemplating dhammas in dhammas, one is mindful. One is mindful by four further means as well … he is called "mindful." Hence: "Therefore a person should always be mindful."
