From the Mahabharata
Vyadha Gita: the butcher who taught a sage
A proud ascetic, Kaushika, is sent to learn from a meat-seller in Mithila. The butcher teaches him plain goodness: don't return evil, repent and resolve, keep envy away, care for your parents, and don't spend your one life making enemies.
Wisdom lives in ordinary people doing ordinary work honestly. Care for your parents.
From the Mahabharata
The parrot who stayed with the withered tree
A hunter's poisoned arrow withers the tree where a parrot has always lived. The parrot refuses to leave it. Indra, moved by its loyalty, restores the tree.
Loyalty means staying through the bad season, not only the good.
From the Mahabharata
The golden mongoose and the handful of flour
At the end of Yudhishthira's lavish horse sacrifice, a half-golden mongoose declares it worth less than a poor family's gift. In a famine, a gleaner, his wife, son and daughter-in-law each gave their last handful of flour to a hungry guest; rolling in the spilt flour turned half the mongoose to gold.
A small gift, honestly earned and given from little, outweighs the grandest show.
From the Ramayana
Bharat rules from a hut for fourteen years
Bharat places Ram's sandals on the throne and lives outside the city in a hut, sleeping on grass, fasting, governing only as a caretaker. The palace's riches are all around him and do not touch him, like a bee in a champak garden.
You can live amid plenty without being owned by it.
