We know from certain sources, where certain practices originated, and why. The derivation of Christian meditation, is Christianity. Trusted. And the practices, themselves, are void of any kind of link (some on CAF in past times have mentioned the term ‘philosophies’) to non-Christian eastern practices, in which the invoking of other ‘gods’ took place, which St. Paul named as being demons. So, if something lacks a source, we are dealing with an unknown, and therefore, could be using a practice known previously for invoking false ‘gods’, by which there is a complicated, real, history, behind it.
This appears to contradict something I said to another poster, when I said that most meditations probably come from previous centuries. But, it doesn’t. Because there are certain types of meditiation, which other religions cannot claim as theirs, because of the simplicity of expression, involved. I can imagine a desert father at prayer, in a cave, sitting or kneeling in silent ‘contemplation’, as another poster called it. Quietly inviting God into prayer, silently, is of such simplicity, that it cannot be claimed by any other religion, as theirs.
As opposed to, a more complex eastern practice, such as Yoga, or something else, that might involve extra areas that one does not fully understand. Things have their references and applications.
‘Meditation’, ‘contemplation’, is probably the same thing. Contemplation is maybe more active on the part of the praying person, than meditation. Although, both are in, and with, God.
