THE PHILOSOPHY OF THE BLUE BARD OF THE CHAIR.
In the forehead is the intellect; In the nape is the memory; In the pate is discretion; In the understanding, memory, and discretion together, is reason; In the lungs is the breath; In the breast is lust; In the liver is the heat;
In the veins is the blood; In the bile is anger; In the spleen is joyousness; In the heart is love; In all these is affection; In the affection is the soul; In the soul is the mind; In the mind is faith; In faith is the Son of God; In the Son of God is imperishable life; In imperishable life is gwynvyd;
Without end; and blessed is he, who rightly exercises the faculties with which God has endued him, in order to attain to endless gwynvyd, for ever and ever. Amen.
