Last of all is that exalted mood when the mind glows and throbs, when reason emits thoughts, as stars blaze light; when the nimbus that overarches the brows of saints in ancient pictures literally represents the effulgence of the mind.

Work done in the lower moods is called mediocre; work done by the mind in the second stage is associated with talent, but when, through birth or ancestry, the mind works ever in regnant and supernal moods, it is called genius.
Affirming that all minds rise into this higher mood at intervals, we may also affirm that all the best work in literature or art or commerce has been wrought during these exalted states when love for the work in hand has rendered the mind luminous and crystalline.
It was love of nature that lent Wordsworth his power to divine nature's secret.

When the poet approached Chamouni and the mountains that gird it round he tells us he was conscious of a shivering from head to foot, with mingled awe and fear; his mind glowed with an indescribable pleasure; his body thrilled as if in the presence of a disembodied spirit; his heart approached nature with an intensity of joy comparable only to that joy which Dante felt when approaching Beatrice.

But when the cares of this world gained upon him and the love of nature faded gradually away in the manner described by him in his "Intimations of Immortality," then also his power to describe nature faded away.

For only when the heart loves can intellect do great work.
His biographer tells us that when Angelo grew old and blind he was accustomed to ask his servant to lead him to the torso of Phidias.
Passing his hands slowly over the broken marble, the sculptor entered into the thought of the great Grecian, and with love for his art glowing in his face and thrilling in his voice, he mused aloud upon the genius of Phidias.
