Light of Valinor

The Light of Valinor was a term that referred not only to the glorious, unsullied light of the Two Trees, but also to the pure wisdom and understanding that those living in the Blessed Realm possessed.
The Light of Valinor derived from light before any fall and is the light of art bound with reason and good bound with beauty.
The Light of Valinor appeared to be a quality that the inhabitants of Aman could spread to others: the Eldar who went there and were instructed by the Valar gained much wisdom and beauty, so that they surpassed all other Elven races in greatness. When the Noldor came back to Middle-earth in the First Age, they spread the Light of Valinor that was in them to the Edain, so that the Edain became a nobler people.
