Very good to point out the fall of the intellect as well as the will.
And yes also regarding spiritual development. I found an on-line pdf
As we said there, the first part consists of the good and honest physical works of mercy and charity. This is the first stage of the active life, as we have already said. The second part of these two lives consists of good spiritual meditations on our own wretchedness, on the sufferings of Christ, and on the joy of heaven.
The first part is good: the second is better, for it is the second stage of the active life and the first of the contemplative. In this part the contemplative and active lives are knit together in a spiritual relationship, and made sisters like Martha and Mary. To such a height of contemplation may an active come, yet no higher except on the rarest occasions, and then by special grace: to such a depth may
a contemplative descend towards the active life, but no lower, except on the rarest occasions, and in times of great need.
The third part of these two lives is caught up in this dark cloud of unknowing, and has many a secret act of love to God as he is. The first part is good, and second better, the third best of all. And this is Mary’s 'best part '.
