Our reasoning depends upon the nature of the senses.
When sense changes, this world becomes different-
Rest and motion, quality and quantity are changed.
It can be said that the world of colour and smell is non-existent,
Earth and sky, house and street, are nothing.
It can be said that all these are dreams or illusions,
Or veils over the countenance of the Divine Person.
It can be said that all is sorcery of the senses,
A deception produced by our eyes and ears.
But the ego does not belong to the universe of colour and smell ;
Our senses do not intervene between us and it.
Eyesight has no access to its sacred precincts,
You can see "self" without eyesight.
The calculation of its days is not through the revolution of the sky;
If you look within, there is no doubt or misgiving about it.
If you say that the "I" is a mere illusion-
An appearance among other appearances-
Then tell me who is the subject of this illusion.
Look within and discover.
The world is visible, yet its existence needs proof!1
Not even the intellect of an angel can comprehend it;
The "I" is invisible and needs no proof
Think awhile and see thine own secret!
The "I" is Truth, it is no illusion;
Don't look upon it as a fruitless field.
When it ripens, it becomes eternal
(Iqbal)
