The form of prayer in which the sentiments expressed are one's own and not those of another person and the expression of these sentiments is mainly, if not entirely, interior and not externalized. Mental prayer is accomplished by internal acts of the mind and affections and is either simple meditation or contemplation. As meditation, it is a loving and discursive (reflective) consideration of religious truths or some mystery of faith. As contemplation, it is a loving and intuitive (immediately perceptive) consideration and admiration of the same truths or mysteries of faith. In mental prayer the three powers of the soul are engaged: the memory, which offers the mind material for meditation or contemplation; the intellect, which ponders or directly perceives the meaning of some religious truth and its implications for practice; and the will, which freely expresses its sentiments of faith, trust, and love, and (as needed) makes good resolutions based on what the memory and intellect have made known to the will.
