“Not only should the ideas in our mind be of high quality but we should make sure that they are in the proper form – clear, precise and classified. It is only then that we can use them easily and most profitably. Vague ideas and unclassified facts, even when they are of great value, cannot be used in thinking of a high order or in the solution of the real problems of life. They are like uncut and unpolished precious stones which may be very valuable but still cannot be used in making jewellery.” (I.K. Taimni. Self-Culture in the Light of Occultism, p. 105)
