This is not for the casual or negative. I'd imagine the penalties for negative use for this sort of thing to be quite severe. If you want to channel a lot of positive energy, please try this, the need is severe:
"That is why what we ask of you at this time is of such vast importance. We ask you to shine your LOVE/LIGHT more brightly than ever before. We ask you to take your LIGHT out from the closet where many of you have had it safely hidden so that you do not have to experience ridicule or criticism from your family and acquaintances, or seem "different." We ask you to take your LIGHT from beneath the basket of compliancy, and rev up the power so that its radiance shines forth for all to see — sweeping wide like the beam of a LIGHTHOUSE, filling the shadows and dangerous shoals with Light so that others may find their way through the obstacles and barriers of fear, hate, guilt, and bigotry."
