The purpose of the whole [the Comedy] and of this portion [the Paradiso] is to remove those who are living in this life from the state of wretchedness, and to lead them to the state of blessedness.
Sta come torre ferma, che non crolla
Giammai la cima per soffiar de' venti.
Be steadfast as a tower that doth not bend its stately summit to the tempest's shock.
