Firstly, i would be thankful if someone provides me a simple explanation of space, time and causation.
Secondly, Vivekananda said in his books, that Brahman, the Absolute has become the universe by coming through space, time and causation. Then again he says, in Brahman the Absolute there is no space, time and causation. Isn't there contradiction in his statement. If there's no time, space and causation in Brahman, then how does Brahman appears through this glass of space, time and causation in the first place?
Here's the excerpt taken from his book,
The Complete Works of Swami Vivekananda, Volume 2- Jnana Yoga
The Absolute has become the universe. By this is not only meant the material world, but the mental world, the spiritual world — heavens and earths, and in fact, everything that exists. Mind is the name of a change, and body the name of another change, and so on, and all these changes compose our universe. This Absolute has become the universe by coming through time, space, and causation. This is the central idea of Advaita. Time, space, and causation are like the glass through which the Absolute is seen, and when It is seen on the lower side, It appears as the universe. Now we at once gather from this that in the Absolute there is neither time, space, nor causation. The idea of time cannot be there, seeing that there is no mind, no thought. The idea of space cannot be there, seeing that there is no external change. What you call motion and causation cannot exist where there is only One. We have to understand this, and impress it on our minds, that what we call causation begins after, if we may be permitted to say so, the degeneration of the Absolute into the phenomenal, and not before; that our will, our desire and all these things always come after that.
Also what exactly Vivekananda meant by
when it is seen on the lower side, it appears as the universe"?
I mean from an Absolute point of view, there are no boundaries or worlds. All there exists is infinite Brahman. So how can there be a lower or upper side in the infinite, boundless Brahman?
