อารัมภบทI shall now explain and expand upon the meaning of the Dhamma theme written above, as a guide for study and practice.

อธิบายบทตั้งTo explain: This saying, "sati lokasmi jāgaro", meaning "Mindfulness is the quality of wakefulness in the world," signifies that mindfulness reminds a person to live heedfully, without absent-mindedness and without neglecting to do good. The word "mindfulness" (sati) means recollection, not being absent-minded, and keeping the mind on the task at hand; it helps one to remember one's duties, what one should do and what one should refrain from. One who has mindfulness is therefore like one who is awake, because he does not let his life run on in heedlessness.

ขยายความบทตั้งSleep here does not mean natural sleep, but is a comparison for heedlessness, carelessness and infatuation with various things until one forgets one's duties and neglects what is right. A person whose mind is asleep in this way is easily overwhelmed by the defilements, like a house whose guard has fallen asleep, giving thieves the opportunity to come in and steal. Mindfulness is therefore like a guard watching the gate of the mind, warning one not to let oneself be carried away by moods. When greed, anger or delusion arises, mindfulness helps one to remember to guard the mind and opens the way for wisdom to consider and hold back words or actions that might cause harm.

ขยายความบทตั้งA teaching in line with this explanation appears in the Jāgara Sutta, which says that when the five faculties are awake, the five hindrances are said to be asleep, and when the five hindrances are asleep, the five faculties are said to be awake. The five faculties, namely faith, energy, mindfulness, concentration and wisdom, are important qualities that support the development of the mind. The five hindrances, namely sensual desire (kāmacchanda), delight in sensual pleasures; ill will (byāpāda), thoughts of harming others; sloth and torpor (thīnamiddha), dejection and drowsiness; restlessness and remorse (uddhaccakukkucca), agitation and worry; and doubt (vicikicchā), wavering uncertainty, are qualities that obstruct the mind from progressing in goodness. The wakefulness of the faculties and the sleep of the hindrances are therefore an image showing a life lived with wholesome qualities, without letting unwholesome qualities take over.

ขยายความบทตั้งThe commentary on the Jāgara Sutta explains that one who is endowed with the five faculties is called awake even while sleeping, because he is heedful and endowed with what is wholesome, while one who is endowed with the five hindrances is called asleep even in other postures, because he is heedless and endowed with what is unwholesome. Therefore, the statement "even while sleeping, one is called awake" means being heedful in the Dhamma; it does not mean that while asleep one is still aware of events or dangers around one all the time.

ประโยคสะพาน + ที่มา ๑The mindful person knows how to review themselves, see their shortcomings, and correct them, and so becomes excellent and better every day than the day before. This accords with the Buddha's saying found in Saṃyutta Nikāya, Sagāthāvagga:

อธิบายบทเชื่อม ๑To explain: It teaches that mindfulness is an important quality that helps us live well each day, because it reminds us not to be careless, not to forget our duties and not to let emotions lead us into wrongdoing. The word "better" here refers to one who is good in the way he lives. When mindfulness is trained together with wisdom and effort, it helps us learn to correct our shortcomings and improve ourselves.

อธิบายบทเชื่อม ๑A careless person may repeat mistakes because he does not review what he has done. One who trains in mindfulness regularly recalls what he has thought, said and done today, and then considers what is good and should be kept, and what is not good and should be avoided or corrected. Reviewing oneself in this way is one method that helps us learn from our mistakes and gradually improve our conduct. This does not mean that a mindful person never makes mistakes, but that when he does, he is ready to learn and improve.

อธิบายบทเชื่อม ๑In the Maṇibhadda Sutta, from which this saying comes, the Buddha showed that mindfulness supports progress and happiness, but mindfulness alone is not enough to be free from enmity. He therefore went on to speak of loving-kindness and delight in harmlessness. This teaching reminds us to train mindfulness together with goodwill towards others, not to use words or actions to cause trouble, and not to hold grudges or seek revenge when conflict arises.

ตัวอย่างในชีวิตIn daily life, a mindful driver pays attention to his driving and does not use his phone while driving, which helps to reduce the risk of accidents. A mindful student listens attentively to the teacher, and when his mind wanders to other things, he returns his attention to the lesson, which helps him to understand what he is learning better. A person who trains in mindfulness, when provoked to anger, has the chance to remember to be careful with his words and actions. This helps him to stop and consider before responding and to choose to act appropriately, instead of letting anger lead to actions he will later regret.

สรุปTo conclude: Those who wish to live heedfully should therefore always train in mindfulness, beginning with paying attention to the task they are doing, and when the mind wanders, recollecting and bringing it back. At the same time, they should train in clear comprehension (sampajañña), that is, self-awareness, to know clearly what they are doing, and use wisdom to consider whether it is appropriate, together with developing other wholesome qualities. Regular training helps one to be circumspect, not to be easily carried away by moods, and not to neglect one's duties and the doing of good. Mindfulness is therefore the quality that helps the mind to awaken from heedlessness. This accords with the Dhamma saying set forth as the theme at the beginning:
