In Buddhism, the Seven Factors of Awakening (Pali: satta bojjhagā or satta sambojjhagā; Skt.: sapta bodhyanga) are: Mindfulness (sati, Sanskrit smṛti). To maintain awareness of reality, in particular the teachings (dhamma). Investigation of the nature of reality (dhamma vicaya, Skt. dharmapravicaya). Energy (viriya, Skt. vīrya) also determination, effort Joy or rapture (pīti, Skt. prīti) Relaxation or tranquility (passaddhi, Skt. prashrabdhi) of both body and mind Concentration (samādhi) a calm, one-pointed state of mind, or "bringing the buried latencies or samskaras into full view" Equanimity (upekkha, Skt. upekshā). To accept reality as-it-is (yathā-bhuta) without craving or aversion. This evaluation of seven awakening factors is one of the "Seven Sets" of "Awakening-related states" (bodhipakkhiyadhamma). The Pali word bojjhanga is a compound of bodhi ("awakening," "enlightenment") and anga ("factor"). Etymology Satta sambojjhagā: satta – seven; bodh – an abstract noun formed from the verbal root *budh- (to awake, become aware, notice, know or understand) corresponding to the verbs bujjhati (Pāli) and bodhati or budhyate (Sanskrit); aṅga – a part of a whole; factor, cause. Pali literature In the Sutta Pitaka's Samyutta Nikaya, the bojjhangas refer to wholesome, mundane factors leading to enlightenment. In the Abhidhamma and Pali commentaries, the bojjhangas tend to refer to supramundane factors concurrent with enlightenment. Sutta Pitaka According to one discourse in the Samyutta Nikaya entitled "Bhikkhu Sutta" (SN 46.5): [Bhikkhu:] "Venerable sir, it is said, 'factors of enlightenment, factors of enlightenment.' In what sense are they called factors of enlightenment?" [Buddha:] "They lead to enlightenment, bhikkhu, therefore they are called factors of enlightenment...." During meditation, one may contemplate the seven Factors of Enlightenment as well as on their antithesis, the Five Hindrances (sensual pleasure, ill-will, sloth-torpor, restlessness-worry, doubt). In addition, one Samyutta Nikaya sutta identifies developing each of the enlightenment factors accompanied by each of the four brahma viharas (lovingkindness, compassion, sympathetic joy, equanimity). In the Samyutta Nikaya's "Fire Discourse," the Buddha identifies that mindfulness is "always useful" (sabbatthika); while, when one's mind is sluggish, one should develop the enlightenment factors of investigation, energy and joy; and, when one's mind is excited, one should develop the enlightenment factors of tranquility, concentration and equanimity. Again according to the Samyutta Nikaya, once when the Buddha was gravely ill he asked Venerable Mahacunda to recite the seven Factors of Enlightenment to him. In such a way the Buddha was cured of his illness. Abhidhamma and commentarial literature In the Visuddhimagga, in
