When secret deliberations drew to a close, King Manuchehr commanded that all which had been spoken remain bound in strict confidence. The monarch then summoned Zal, desiring to put his intellect and noble lineage to a supreme trial, for a kingdom requires champions who possess not merely overwhelming prowess in battle, but cosmic insight and profound wisdom.
The clear-sighted sages and illustrious Mobads gathered in the royal presence, seating Zal among them. Thereupon, a sharp-witted priest stepped forward and posed the first riddle: 'Speak to me of twelve tall, vibrant cypresses, each bearing thirty sturdy branches—a count that in the Persian tongue never increases nor diminishes.'
Before the echoes of the first mystery faded, a second Mobad arose and asked: 'O exalted noble, tell us of two priceless, swift steeds—one as dark as a sea of black pitch, the other radiant as shimmering white crystal. Both are in perpetual, frantic pursuit of one another, yet neither ever catches the other.'
A third priest continued the questioning: 'Consider thirty horsemen who parade before the King; when you count them, one seems missing, yet when you gaze again, thirty stand fully present.'
The fourth Mobad turned the test toward the mysteries of mortality: 'Describe a lush meadow, overflowing with greenery and flowing streams, into which a formidable man enters carrying a massive, razor-sharp scythe. He mows down both green and dried shoots indiscriminately, never pausing his merciless work.'
The fifth Mobad brought forth a cosmic cipher: 'I beheld two lofty cypresses rising from a surging ocean like reeds. A mystical bird makes its nest upon them—resting on one at dusk, and flying to the other at dawn. When it departs from one tree, its leaves dry and wither; when it alights upon the other, the air turns sweet with the scent of musk. Thus, one tree ever flourishes while the other languishes in mourning.'
Finally, another Mobad presented the deepest dilemma of existence: 'Upon a mountain peak, I found a citadel of absolute strength and majesty. Yet men departed from that glorious city to settle in a thorny desert upon the plain. There they raised palaces reaching toward the moon, enslaved servants, and utterly forgot that celestial city of their origin. Suddenly, a violent earthquake strikes, swallowing their worldly structures into darkness, forcing them back to that initial mountain citadel in dire distress and eternal contemplation.'
The sage concluded: 'Unveil these secrets from behind their curtains and speak them clearly before the princes of the realm; for if you illuminate these hidden truths, you shall transform the black dust of earth into pure musk.'
