Every expenditure of force on the part of a Master or Teacher is subjected to wise foresight and discrimination. Just as we do not put university professors to teach the beginners, so the Masters themselves work not individually with men until they have attained a certain stage of evolution and are ready to profit by their instruction. Secondly, we must remember that each of us is recognized by the brilliance of his light. This is an occult fact. The finer the grade of matter built into our bodies, the more brilliantly will shine forth the indwelling light.
Light is vibration, and through the measurement of vibration is fixed the grading of the scholars.
Hence nothing can prevent a man's progress forward if he but attends to the purification of his vehicles. We are all graded, therefore, if it may be so expressed, according to the magnitude of the light, according to the rate of vibration, according to the purity of the tone and the clarity of the color. Who our Teacher is depends therefore upon our grading. Similarity of vibration holds the secret. We are frequently told that when the demand is forceful enough the Teacher will appear.
