"The richness of Sanskrit language is almost beyond belief. Many centuries ago that language contained words to describe states of the conscious and the subconscious and the unconscious mind and a variety of other concepts which have been evolved by modern psychoanalysis and psyche-therapy. Further, it has many a word, of which there is no exact synonym even in the richest modern languages. That is why some modern writers have been driven occasionally to use Sanskrit words when writing in English."
