To need more light is a sign that more light is coming...and it has become intoxicating to you, hence your "desire" energy, one of the three poisons that keeps us away from that all encompassing light, and being filled with more light, is somehow, getting in the way. The three poisons that keeps us from being totally submerged and surrendered to that ALL-LUMINOUS LIGHT (aka God, aka Samantabhadra) is basically desire, anger and ignorance.
