GAI represents the relative separation of object colors illuminated by a light source; the greater the GAI, the greater the apparent saturation or vividness of the object colors. As a result, light sources which balance both CRI and GAI are generally preferred over ones that have only high CRI or only high GAI.

Tafsir is one of the earliest academic activities of Muslims. According to the Quran, Muhammad was the first person who described the meanings of verses for early Muslims. Other early exegetes included a few Companions of Muhammad, like ʻAli ibn Abi Talib, ʻAbdullah ibn Abbas, ʻAbdullah ibn Umar and Ubayy ibn Kaʻb. Exegesis in those days was confined to the explanation of literary aspects of the verse, the background of its revelation and, occasionally, interpretation of one verse with the help of the other. If the verse was about a historical event, then sometimes a few traditions (hadith) of Muhammad were narrated to make its meaning clear.

What is the Arabic term for Quranic exegesis?
Answer: Tafsir

Zen Buddhist teaching is often full of paradox, in order to loosen the grip of the ego and to facilitate the penetration into the realm of the True Self or Formless Self, which is equated with the Buddha himself.[note 14] According to Zen master Kosho Uchiyama, when thoughts and fixation on the little "I" are transcended, an Awakening to a universal, non-dual Self occurs: "When we let go of thoughts and wake up to the reality of life that is working beyond them, we discover the Self that is living universal non-dual life (before the separation into two) that pervades all living creatures and all existence." Thinking and thought must therefore not be allowed to confine and bind one.

What type of self is equated with the Buddha?
Answer:
True Self
