The Buddha said, "Disciples of the Buddha, if you wish to repay
their kindness, then for the sake of your parents, print this
Sutra. This is truly repaying their kindness.
Printing sutra is surely great merits and blessings! As for this
context, I think it has a broader understanding rather than merely
printing the mentioned sutra. Although I personally did not attain
a slightest, my opinion is that all sentient beings that one in
contact with in any moment is our parents and ourselves
as well.
