The Buddha answers to the Deva
On a certain day when the Buddha dwelt at Jetavana, the garden of Anathapindika, a celestial deva came to him in the shape of a Brahman enlightened and wearing clothing as white as snow. The deva asked, What is the sharpest sword? What is the deadliest poison? What is the fiercest fire? What is the darkest night?" The Buddha replied, The sharpest sword is a word spoken in wrath; the deadliest poison is covetousness; the fiercest fire is hatred; the darkest night is ignorance. The deva said, What is the greatest gain? What is the greatest loss? Which armour is invulnerable? What is the best weapon? The Buddha replied, The greatest gain is to give to others; the greatest loss is to greedily receive without gratitude; an invulnerable armor is patience; the best weapon is wisdom. The deva said, Who is the most dangerous thief? What is the most precious treasure? Who can capture the heavens and the earth? Where is the securest treasure-trove? The Buddha replied, The most dangerous thief is unwholesome thought; the most precious treasure is virtue; the heavens and the earth may be captured by the mind's eye; surpassing rebirth locates the securest treasure-trove. The deva asked, What is attraction? What is repulsion? What is the most horrible pain? What is the greatest enjoyment? The Buddha replied, Attraction is wholeness; repulsion is unwholesomeness; the most tormenting pain is bad conscience; the height of bliss is redeemed awakening. The deva asked, What causes ruin in the world? What breaks off friendships? What is the most violent fever? Who is the best physician?" The Buddha replied, Ruin in the world is caused by ignorance; friendships are broken off by envy and selfishness; the most violent fever is hatred; the best physician is the enlightened one; The deva continued, Now I have only one doubt to resolve and absolve: What is it fire cannot burn, nor moisture corrode, nor wind crush down, but is able to enlighten the whole world. The Buddha replied, Blessing! Neither fire, nor moisture, nor wind can destroy the blessing of good deeds, and blessings enlighten the whole world. Hearing these answers, the deva was overflowing with joy. Then clasping hands, bowed down in respect and disappeared suddenly from the presence of the Buddha.
