The philosophical meaning of Einstein's discoveries--that the nature of the world depends on the nature of its relation to the one who sees it, that we cannot truly speak about any object independently of the observer, and that time is the hallmark of this relativity--is in perfect accordance with our own doctrine. Whatever is seen, is seen by the mind. Apart from the mind we know nothing of its existence and apart from the mind the thought of time could not arise for us. In short, every existent object is wholly relative to the subject--Mind.
