In one sense, these letters refer to the states of holiness. The first means "Free thyself from the promptings of self, then approach thy Lord." The second means "Purify thyself from all save Him, that thou mayest offer up thy life for His sake." The third means "Draw back from the threshold of the one true God if thou art still possessed of earthly attributes." The fourth means "Render thanks unto thy Lord on His Earth, that He may bless thee in His heaven, albeit in the realm of His unity His Heaven is the same as His Earth." The fifth means "Remove from thine eyes the veils of limitation, that thou mayest learn that which thou knew not of the stations of holiness."
