"If a man could know what lieth hid in this one verse, it would suffice him..."

"On this plane, the traveler meeteth with many a trial and reverse. Now is he lifted up to heaven, now is he cast into the depths. As it hath been said: “Now Thou drawest me to the summit of glory, again Thou castest me into the lowest abyss.” The mystery treasured in this plane is divulged in the following holy verse from the Súrih of THE CAVE: 3

 “And thou mightest have seen the sun when it arose, pass on the right of their cave, and when it set, leave them on the left, while they were in its spacious chamber. This is one of the signs of God. Guided indeed is he whom God guideth; but for him whom He misleadeth, thou shalt by no means find a patron.”

If a man could know what lieth hid in this one verse, it would suffice him. Wherefore, in praise of such as these, He hath said: “Men whom neither merchandise nor traffic beguile from the remembrance of God….” 4"
