Whosoever assumes a religious garb pleases not God even a bit. O ye men, understand this clearly in your minds, that God is attained not through showmanship. They who practice deceit, attain not Deliverance in the Hereafter. They do so only to accomplish the affairs of the world and even the kings worship them for their appearance! But through showmanship, God is attained not, howsoever one searches. He who subdues his mind alone recognizes the Transcendent God.

In the City of Death, there is pitch darkness and huge clouds of dust, neither sister nor brother is there. This body is frail, old age is overtaking it.
