Worth keeping in mind is that an arahant needs to learn from a Buddha to become enlightened, so if the story in question means the prince became an Arahant (epic for one awakened) before meeting the Buddha, that is impossible.
Was said by monk yuttadhammo
My person would reject such a categorical statement but is of course open to give it a prove.
No doubt that an awakened would seek out for the Sangha, but especially this days, although the Dhamma might be traceable, such as the Sangha is not sure.
So what is actually told about the appearances of a Paccecabuddha and Awakened, (such a person) being told as even someone who may be in the position to rebuke the monks?
