In Buddhism, the seven factors of awakening (Pali: satta bojjhaṅgā or satta sambojjhaṅgā; Skt.: sapta bodhyanga) are:

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").

Satta sambojjhaṅgā:

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.

According to one discourse in the Samyutta Nikaya entitled "Bhikkhu Sutta" (SN 46.5):

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 (loving kindness, 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.
