Base on the scenario been described in the question, the statement that expresses the main theme of the short story medicine in the bag was "Learn From Your Elders" or "The Young Learning from the Experienced". This theme refers to when a child, or a person younger than the adult/elder, learns from their adult/elder. In the short story, the great-grandfather teaches Martin the value of the Medicine Bag.

The Russian language itself is not based on Greek, but its alphabet is. The Cyrillic alphabet is very closely based on the Greek alphabet, though it contains about a dozen additional letters, which were created in order to represent sounds found in Russian but not in Greek.
