““We cannot gain an essential knowledge of man through any method that is based on externalization of man's inner being and the placing of this externalized man, of the man who stands at the rim of the wheel of existence, as the subject that knows. If "essential" has any meaning at all, it must be related to the essence, to the Centre or axis which at once generates the spokes and the rim. Only the higher can comprehend the lower, for to "comprehend" means literally "to encompass", and only that which stands on a higher level of existence can encompass that which lies below it. The essence of man, that which is essential to human nature, can be understood only by the intellect, through "the eye of the heart" as traditionally understood.””
