To One's Remotest Descendants

Kindness always come back to the person oneself or if the one is dead, to the one's kin.
My grandma (my mom's mother) died more than five years ago. She didn't teach how to make miso paste from soybeans. May be her children were too busy for other things... I don' know.
But she thought it to a neighboring woman. My grandma did good to her when the woman was buried and thought her how to make miso paste. Then the woman keeps making miso for over 30 years, and now one of my aunts are going to learn. The woman said to the aunt "Your mother treated me nicely and thought me how to make miso paste. So now I want to teach this technique to you - her daughter."
One's kindness flows continuously to posterity. The shape might be changed, but the spirit is the same.
I'm sure that my grandma were treated nicely from other person.
