Parroting a formulaic prayer does no more good than spinning a prayer wheel. It is mechanistic with no thought or feeling behind it.

Parroting a formulaic prayer does no more good than spinning a prayer wheel.

But you can't assume that that is the case in every case, as the many witnesses here attest. The prayer seems to be yielding good fruit.

And as Sans-Culotte mentioned above, one can use repetitive prayer as a "background" for deeper meditation. Such is the case with the much-maligned Rosary. Repeating the "Hail Mary's" can clear every day worries and distractions from the mind and free one to meditate on Christ's life, death and resurrection.
