We may conclude with the above demonstration. Verily the Esoteric doctrine may well be called in its turn the "thread-doctrine," since, like Sutratman or Pranatman, it passes through and strings together all the ancient philosophical religious systems, and, what is more, reconciles and explains them. For though seeming so unlike externally, they have but one foundation, and of that the extent, depth, breadth and nature are known to those who have become, like the "Wise Men of the East," adepts in Occult Science. --H.P. Blavatsky Personal and Impersonal God At the outset I shall request my readers (such of them at least as are not acquainted with the Cosmological theories of the Idealistic thinkers of Europe) to examine John Stuart Mill's Cosmological speculations as contained in his examination of Sir William Hamilton's philosophy, before attempting to understand the Adwaita doctrine; and I beg to inform them beforehand that in explaining the main principles of the said doctrine, I am going to use, as far as it is convenient to do so, the phraseology adopted by English psychologists of the Idealistic school of thought. In dealing with the phenomena of our present plane of existence John Stuart Mill ultimately came to the conclusion that matter, or the so-called external phenomena, are but the creation of our mind; they are the mere appearances of a particular phase of our subjective self, and of our thoughts, volitions, sensations and emotions which in their totality constitute the basis of that Ego. Matter then is the permanent possibility of sensations, and the so-called Laws of matter are, properly speaking, the Laws which govern the succession and coexistence of our states of consciousness. Mill further holds that properly speaking there is no noumenal Ego. The very idea of a mind existing separately as an entity, distinct from the states of consciousness which are supposed to inhere in it, is in his opinion illusory, as the idea of an external object, which is supposed to be perceived by our senses. Thus the ideas of mind and matter, of subject and object, of the Ego and external world, are really evolved from the aggregation of our mental states which are the only realities so far as we are concerned. The chain of our mental states or states of consciousness is "a double-headed monster," according to Professor Bain, which has two distinct aspects, one objective and the other subjective. Mr. Mill has paused here, confessing that psychological analysis did not go any further; the mysterious link which connects together the train of our states of consciousness and gives rise to our Ahankaram in this condition of existence, still remains an incomprehensible mystery to Western psychologists, though its existence is but dimly perceived in the subjective phenomena of memory and expectation.
