We cannot but acknowledge the capacity of the Indians for philosophic speculations, and the vigour of thought which for the first time in history maintained the thesis that our senses deceive us; that all which surrounds us is appearance and deception--which denies the whole world of things, and in opposition to the evidence of the tangible and actual world, boldly sets up the inward capacity of knowledge, as a criterion against which the evidence of the senses is not to be taken into consideration. For a long time the actual world had been resolved into the transcendental world of gods and saints; this is now contracted into a simple substance, beyond and besides which nothing exists but appearance. Instead of the appearance of the sensible world, in which there is no being, there exists one real being, the one invisible world-soul, which allows the corporeal world to arise into appearance from it like airy bladders, and then again to sink back whence it came. This universal deity is conceived as a being at rest; its activity and development into a sensible world is only apparent. It is a Pantheism which annihilates the world; matter and nature are completely absorbed by the world-soul, are plunged and buried in it; the soul of a man is a being only apparently separated from the world-soul. From these notions the mission of a man becomes clear. He must turn from appearance; he must unite with the world-soul by recognising the fact that all perceptions and emotions come from the world of phenomena, and therefore do not really exist; he must rise to the conception that only Brahman exists, and that man is Brahman. If from an ancient period the Indians were of opinion that they could draw down the gods to men by the holy spirit ruling in their prayers and sacrifices--if the mortification of the flesh in penances can give divine power and force to men--their philosophy is no more than consistent, when by recognising the worthlessness of sensible existence it allows Brahman to wake in the human spirit, and thus re-establishes the unity of man with Brahman.
