Gudarz and Tus Dispute before Kavus

From B10.33, The Kingship Is Debated before Kavus. It illustrates B10.33.6–17 (to B10.33.28):

B10.33.6
Then Tus and Gudarz came, their duty known,And spoke before the king in measured tone.
B10.33.7
Tus said: “If you are weary of what kingship brings,If weary too of throne and crown of kings,
B10.33.8
Then let your son inherit throne and might;The diadem and treasure are his right.
B10.33.9
Why should a grandson take the royal place,While still a son remains of kingly race?
B10.33.10
In him the Kayan farr and burz appear;He girds himself like lion without fear.”
B10.33.11
Then Gudarz said: “Your wisdom is too small;No wise man counts you wise among them all.
B10.33.12
No man has equaled Siavash in worth,So generous, noble, gentle on this earth.
B10.33.13
And this world-seeking prince, Siavash’s son,In face and form, the two would seem as one.
B10.33.14
Though on his mother’s side he springs from Tur,Yet royal blood and justice both endure.
B10.33.15
No man in Iran or Turan is his peer;Why speak such raw and unripe counsel here?
B10.33.16
You have not seen his stature, face, and frame,Nor known the mehr that shines about his name.
B10.33.17
He crossed the Jihun, seeking not a boat;Kayanian farr and sense kept him afloat.
