Speculations of this last type have existed from a much earlier period in the Eastern civilizations, particularly in those areas affected by Hindu philosophy. For example, in the Sánkhya or Yoga-Sútras by Patánjali, we find a very radical distinction between the external world and the individual soul or self. But for Sánkhya, the "external world" includes everything that could possibly be an object of consciousness--physical objects and their relationships, sensations and imaginations, dreams, memories, expectations, etc. In other words, for Sánkhya, (...) our thoughts or desires, far from being the "cause" of the external world as in some forms of Western idealism, are simply other aspects of the external world itself, that is, merely particular items in the totality of our consciousness. On the other hand, the individual soul or self is only the spectator of this consciousness and not ordinarily conscious of itself. If the self were to become conscious of "itself" in the same way that it was conscious of all other objects, all that it would really be aware of would be another object of consciousness---the mere idea of itself, while it would remain the unknown knower. Nevertheless, realizing that a completely "unconscious self" would be simply a postulate of thought and therefore part of the external world, the Sánkhya-Sútras emphasize that the self can become aware of itself by another and more intuitive means.
