Look thro' a glass Yellow,
Everything appears Yellow.
And thro' a dark glass,
So dark an object looks.
These colored visions
At once disappears
For both the eyes
Freed from the glass.
In a semi-darkness
A curled rope looks
Like a live serpent,
To one's eyes distant.
A lamp post fused,
In one's vision confused,
As a ghost appears,
Keeping him in fears.
These visions distorted
Aren't the superimposed
Mental projection of ours
O'er the dormant objects?
Yes, there's no harm
To keep the mind calm
Then object looks the same
With no change of name.
