This is a gentle, helpful manual for meditation aimed at gratitude and spiritual growth, rather than harsher disciplines of penance. Fr. Faber offers guidance on good resources and texts for guided meditation, some history, and spiritual examples. This is written from a distinctly Catholic perspective, but may also be welcoming to "Catholic-adjacent" believers such as Episcopalians. It's not intended for non-religious meditation.
Recommended with the above caveat.
