If it is better to be blind here than to see--and the Indian will tell you it often is, because it shuts out all the distracting objects of the physical plane--if you are prepared to say that, and say: "Yes, I would rather be blind than see," then you may go on to denounce seeing on the astral plane.

But if you value your physical sight, why not value the astral sight--it is a stage higher--as well?
and the mental sight--which is a stage higher yet--as well?
Why denounce astral and mental, and praise up the physical?
Why admire the power of sight of the painter, who sees more shades than you can see, and denounce the sight of the clairvoyant, who sees very much more than the cleverest painter?
They all belong to the object world; they all lead the Self away from the realisation of himself, and they are all exactly on the same level.

It seems strange when one sees the same person exalting the psychic on the physical plane and denouncing it on the astral and mental.
But now let us turn to "spirituality" and see what that means.

"The Self-realisation of the One"; not the declaring that all men are one, that all men are brothers: we can all do that.

Anyone who has reached a certain stage of intellectual knowledge will recognise the unity of mankind; will say, with the writer in the Christian book, that God has made all men of one blood--quoted again from what is called a Pagan book.
