In Theology, Divine Light, also called Divine Radiance or Divine Refulgence, is an aspect of Divine Presence, specifically an unknown and mysterious ability of God, Angels, or Human Beings to express themselves communicatively through spiritual means, rather than through physical capacities.
The term Light has been used in Spirituality, Vision, Enlightenment, Darshan, Tabor Light. Bible commentators such as Ritenbaugh see the presence of light as a metaphor of truth, good and evil, knowledge and ignorance. In the first Chapter of the Bible, Elohim is described as creating light by fiat and seeing the light to be good. In Hinduism, Diwali the festival of lights is a celebration of the victory of light over darkness. A Mantra in Bṛhadāraṇyaka Upaniṣad (1.3.28) urges God to ‘from darkness, lead us unto Light’.
Various local Religious concepts exist:
Inner Light – Christian concept and Quaker doctrine
An Noor – Islamic term and concept
Ein Sof – in Rabbinic Judaism
Tabor Light – in Eastern Orthodox theology
Theoria – in Christian theology, illumination on the path to theosis
Ayat an-Nur – in Arabic, the Sign of Light
Light is the core concept in Iranian Mysticism. The main roots of this thought is in the Zoroastrian beliefs, which defines The supreme God Ahura Mazda as the source of light. This very essential attribute is manifested in various schools of thought in the Iranian Religions and philosophy. Latter this notion has been dispensed into the whole Middle East, having a great effect of shaping the paradigms of different religions and philosophies emerging one after another in the region. After the Arab invasion, this concept has been incorporated into the Islamic teachings by Iranian thinkers, most famous of them Shahab al-Din Suhrawardi, who is the founder of the illumination philosophy.
Although this school had stemmed from the Iranian culture and beliefs, it has spread far into Europe and can be seen and traced in the teachings of the Enlightenment era, Renaissance movement, and even the secret cults as early Illuminati.
In the terminology of Sant Mat Light and Sound are the two main and expressions of God and from them all the creation comes into existence. Inner Light (and Inner Sound) can be experienced with and after an initiation by a competent Guru during meditation, and are considered the better way to reach Enlightenment.
Eastern Orthodox Church
In the Eastern Orthodox tradition, the Divine Light illuminates the intellect of man through ‘theoria’ or contemplation. In the Gospel of John, the first few verses describe God as Light. “In Him was life and the life was the light of men. And the light shines in the darkness and the darkness did not comprehend it.” John 1:5 Christ also professes to bring the Divine Light to mankind. “I am the light of the world” John 8:12 The Divine Light is also called the Tabor Light which the apostles witnessed at the Transfiguration.
