Read the story Hide The image above is from a painting entitled "Two Birds in a Tree" by Jeffery Courtney. Based on verses from the Mundaka Upanishad

Two birds, inseparable friends, cling to the same tree. One of them eats the sweet fruit, the other looks on without eating. On the same tree man sits grieving, immersed, bewildered by his own impotence (an-îsâ). But when he sees the other lord (îsâ) contented and knows his glory, then his grief passes away. When the seer sees the brilliant maker and lord (of the world) as the Person who has his source in Brahman, then he is wise, and shaking off good and evil, he reaches the highest oneness, free from passions.
