Hi momper, the direct translation of this phrase is
El se encontró (a si mismo) claro.
But of course this make no sense at all, because we need to look for the context:
clear in spanish could be according to the pourpose of the complement, here some examples
El se encontró: libre (free, from debts, punishments, from jail, etc)
transparente (this could be only possible if you are reading the life of the invisible man)
puro (free from any defect or impurity in body or soul)
vacío (empty)
if nothing of these helps, hopefully you can add more context to make the statement clearer. Saludos desde México, amigo momper
