Some years ago, I heard a retired Lutheran priest ponder, in radio, about the concept of a prayer, and whether, as an edge case, an unborn child could be able to pray, with the child of that age having no understanding on the required concepts. This is apparently one of those questions that people ponder under the umbrella of philosophy of religion. His conclusion was that prayer was about harmonizing one's self with the universe. It's a beautiful thought, (and I think religions, of all kinds, are really good at providing the fertile ground for thoughts like these).

It's akin to how the saying goes, that when we argue, we need to reach the same wavelength where the other one is to reach an understanding.

In communication studies or sociology or linguistics or one of those fields, there's the idea that communication is about making pacts about meanings, and finding the common ground to understand and delimit the message.

In a sense, from that basing, one could argue that understanding can be seen as an act of harmonizing. I think there's something universal in it.
