"Beats there a heart within that breast of thine, Then compass rev’rently its sacred shrine; For the true spiritual K‘aba is the heart And no proud pile of perishable art, When God ordained the pilgrim rite, that sign Was meant to lead thy heart to things divine, A thousand times he treads that round in vain, Who e’en one human heart would idly pain."
