“As I have said before, I do not want anyone to feel bound by my words or thoughts. I only want to offer an example for those who may wish to follow it; let anyone improve it who is able to do so and let him meditate either upon all commandments at one time or on as many as he may desire. For the mind, once it is seriously occupied with a matter, be it good or evil, can ponder more in one moment than the tongue can recite in ten hours or the pen write in ten days. There is something quick, subtle, and mighty about the mind and soul.”
Luther, Martin. “A Simple Way to Pray” (1535) Luther’s Works Vol. 43. Philadelphia: Fortress Press, 1969, page 207.
comment: Luther on meditation, strongly advocating it, clearly declaring its benefits. And NOT wanting people to feel bound by his words, he basically says ‘this is the way I pray, but you should pray however works for you.’ I find his words here refreshing.
