One of the brothers was saying to me: “At first, because my intellect was not accustomed to it, when the light of the Holy Trinity was appearing in it to unite with it in imperceptible simplicity, deprived of understanding because of stupefaction at the light of Life; when it perceived the radiance unifying it, it was overcome with fear that it might never again return to itself.” 

     But when the brother became accustomed to the beatitude beyond all blessings and received the experience of its ineffable delight, and felt the strength which he acquired by it against the passions and against the demons: he saw the splendour of his intellect which on account of the beatitude became like God and he saw the familiarity he partook with Him in everything as a son to a father.
