"Here Hindus are asked to take lessons in Advaita from a man whose sole occupation in life was torturing Upanishadic texts into the dogmatic framework of a gross monolatry. It is difficult for a Christian missionary to renounce the role of a teacher even on subjects about which he knows next to nothing. In the case of Henri Le Saux there was an added difficulty: he was a poet. The flow of mellifluous phrases, particularly in his native French, was mistaken by him for mystic experience. One has to read his writings in order to see how he became a victim of his own word-imageries and figures of speech. Silencing of the mind, which is a sine qua non for spiritual experience according to all Hindu scriptures on the subject, remained a discipline which he never learnt. Small wonder that the man ended as a neurotic."
