O the pity! that man should deprive himself of this goodly gift, this imperishable bounty, this everlasting life.  It behooveth him to prize this food that cometh from heaven, that perchance, through the wondrous favors of the Sun of Truth, the dead may be brought to life, and withered souls be quickened by the infinite Spirit...

We feed our bodies and minds, but few thing about feeding the spirit and soul.  The food of the spirit and soul is God's Light which come to us through the Spiritual Sun, referred to in this quote as the Sun of Truth.
