Fear of the Light
We are the Lords of Light who come to talk to you about when a Meditator cannot merge with the Light.
It is mainly because of Fear, as has been suggested. Fear of the unknown and also trying to analyze what is happening and the mind giving a running commentary. Sometimes the Light can be so bright, like the Sun, people would automatically shield themselves from the Light with their hand. So during Meditation when the Light comes, it cannot be shielded, and therefore the Meditator loses their concentration and the Light disappears.
The only way to combat this is to think of the Light as a trusted friend, the best friend they will ever have, or need. So when it appears, they would automatically want to merge with it, because they know that they will receive Loving Energy, and realize, eventually, that Light is their Higher Nature, their Essence. The Light of God.
