Whether this rule was instituted by the Buddha or not (and there might well have been a valid reason for it back in ancient India of 2600 years ago that we in the modern world cannot now comprehend), I'm not going to concern myself any longer that I cannot see it's necessity. The entire pali canon is available online for us laypersons to read, anyway. And if we study some basic pali, we can train ourselves
to recite the entire tipitaka - in pali
- without having to ask a monk to first recite it for us. And so to worry any further about this little rule, for me, would be like seeing a large and beautiful elephant walking by, and noticing that a bit of vine or creeper was caught in one of it's toenails. So I'm just letting it go now. But I thank everyone who commented.
Then the Blessed One, picking up a tiny bit of dust with the tip of his fingernail, said to the monk, "There isn't even this much form...feeling...
perception...fabrications...consciousness that is constant, lasting, eternal, not subject to change, that will stay just as it is as long as eternity."
