Regarding "Becoming a wheel-turning king": there are four wheel-turning kings: gold, silver, copper, and iron wheels, ruling over four, three, two, and one world respectively.

Sengzhao says: "Had the Buddha not gone forth from home, he should have become a gold-wheel king, ruling over four worlds. Had Rāhula not gone forth from home, he should have become an iron-wheel king, ruling over one world." Because what he renounced was not light and what he anticipated was bound to be momentous, [the elder] asked about its benefit.
