From the Mahabharata
Manki's song: desire, I know your root
Manki spends all he has on a pair of oxen; both are killed in an accident. In his despair he sees through desire: it is born of his own imagining, and he resolves to forgive insults and stop feeding it. Bhishma adds Janaka's verse on owning nothing.
Desire grows from what we imagine. Stop feeding it, and it fades.
From the Mahabharata
Markandeya and the child on the banyan leaf
At the end of an age, the sage Markandeya drifts alone over a flooded world and sees a radiant child on a banyan branch. The child draws him inside his body, where he sees all the worlds, then asks if he has been resting, tired. Narayana explains he showed himself because he saw Markandeya's distress. Markandeya tells the Pandavas that this child is Krishna, sitting with them.
When everything you knew is underwater, you have not been forgotten; you are being held.
From the Mahabharata
Do right without reward, and keep working
Draupadi questions a world where the good suffer; Yudhishthira answers that he does right because it is right, not for reward. Draupadi replies that effort still matters: fate rewards no one who waits.
Do right for its own sake, then work as if it all depends on you.
From the Ramayana
Sampati's burned wings
The search party, past its deadline with no news, sits down by the sea to die. A huge old vulture, Sampati, overhears them talking of his brother Jatayu. He tells them how pride once made him fly too close to the sun and burn his wings; a sage told him they would grow back when he helped Ram's messengers. He tells them where Sita is, and his wings grow back as he speaks.
Even after the fall your pride caused, you can still be useful, and hope can return.
