The Great Rays - Words used in A Course in Miracles

      A Course in Miracles refers to the inner manifestation of Truth as "the Great Rays" - which have been reduced to a spark, when obscured by a belief in a body.

In many only the spark remains, for the Great Rays are obscured. Yet God has kept the spark alive so that the Rays can never be completely forgotten. If you but see the little spark you will learn of the greater light, for the Rays are there unseen. Perceiving the spark will heal, but knowing the light will create. Yet in the returning the little light must be acknowledged first, for the separation was a descent from magnitude to littleness. But the spark is still as pure as the Great Light, because it is the remaining call of creation. Put all your faith in it, and God Himself will answer you.         T-10.IV.8

The cornerstone of God's creation is you, for His thought system is light. Remember the Rays that are there unseen. The more you approach the center of His thought system, the clearer the light becomes. The closer you come to the foundation of the ego's thought system, the darker and more obscure becomes the way. Yet even the little spark in your mind is enough to lighten it. Bring this light fearlessly with you, and bravely hold it up to the foundation of the ego's thought system.   T-11.in.3:2-7.

As the ego would limit your perception of your brothers to the body, so would the Holy Spirit release your vision and let you see the Great Rays shining from them, so unlimited that they reach to God. It is this shift to vision that is accomplished in the holy instant.     T-15.IX.1:1,2.

The little spark that holds the Great Rays within it is also visible, and this spark cannot be limited long to littleness.       T-16.VI.6:3.

You have found your brother, and you will light each other's way. And from this light will the Great Rays extend back into darkness and forward unto God, to shine away the past and so make room for His eternal Presence, in which everything is radiant in the light. T-18.III.8:6,7.

God's Son … . Within himself he has no needs, for light needs nothing but to shine in peace, and from itself to let the rays extend in quiet to infinity.       T-13.VII.13:5,7.
