The knees of these ascetics are, as if, bended on the mountain of Sina. They do not carry their ego in their eastward journey. The garb of those strangers is a mere sheet of Divine secrets. In fact the Divine love, covers them up from head to toe.
Note: Shah has often described the sheet of cloth as being the raiment of holy men. In fact all apostles of Allah, more particularly the Prophet of Islam, generally clad themselves in one sheet as it was less cumbersome. Allah so much appreciated this garment that in Chapter Al-Muzzamil of the Quran, He addressed the Prophet as “the wearer of the sheet”. This practice of the apostles was followed by other holy men including the nomad ascetics.

Yogis knees as if on mount Sinai are bent,
Going to spiritual destination, yogis carry not ego with them,
They are wrapped in the sheet of sacred secrets,
With love Divine from head to toe they are covered.
