Wisdom is the knowledge which manifests only from the inner being

"Intellect is the knowledge obtained by experience of names and forms; wisdom is the knowledge which manifests only from the inner being; to acquire intellect one must delve into studies, but to obtain wisdom, nothing but the flow of divine mercy is needed; it is as natural as the instinct of swimming to the fish, or of flying to the bird. Intellect is the sight which enables one to see through the external world, but the light of wisdom enables one to see through the external into the internal world.” - Hazrat Inayat Khan
