I call it the gift of spiritual discernment....
This then is the message which we have heard of him, and declare unto you, that God is light, and in him is no darkness at all. -
1 John 1:5
If E = mc2 then we can divide and conclude that...
Mass (m) = Energy (E/c2)
And there are three varieties...
Natural E/c2 - All mass is basically cooled plasma
Mental E/c2 - Mentally, A mathematical formula, but this has chemical and spiritual properties as well.
Spiritual E/c2 - E (motivation, warmth, love) / c2 (faith, hope, charity, joy)
Comparing the light and the darkness, the opposite of E/c2 would be z (absolute zero)/ c (darkness)...
Natural z/d - Nothing, empty space.
Mental z/d - Again nothing but empty space.
Spiritual z/d - z (laziness, coldness, hatred / d (fear, despair, greed, sorrow)
And in the middle we have the world of the flesh. We then have the ability to discern flesh, light, goodness, evil, coldness, warmth, on the spiritual level.
