"At this time, the Great Invocation is the greatest aid to humanity. The fulcrum, the axis of the Great Invocation, is Christ - the reappearance of the great Lord, [the] Christ...a living individual... Mantrams are like chemical or geometrical formulas; changing one word gives the mantram an entirely different result, or makes it misleading, dangerous or useless. Mantrams are transmitters of energy. When the transmitter is not constructed in a particular order, the energies can be destructive or negative, creating confusion and chaos in the subtle planes of human endeavor. Many mental disorders are the result of a misuse of prayers, mantrams and chanting. Let us not forget that the Hierarchy uses the Great Invocation in its original form every day.... Those who, with good intentions, want to change the Great Invocation, would do better to create a totally different invocation of their own - instead of distorting a masterpiece painting with their unskilled brush."
