Maluta Jataka On this occasion,the Buddha while residing at Jetavana, told the story about two members of the monks who joined the Order, when they were of mature years. Tradition mentioned that one was known as Monk Dark and the other was Monk Light. They were forest monks in the Kosala country. Now one day, Light said to Dark: "Venerable sir, at what time does that known as cold appear?" "It appears in the dark half of the month." On another day, Dark asked Light: "Venerable sir, at what time does that called cold appear?" And Light replied: "It appears in the light half of the month." As they could not resolve this problem, it was brought to the Buddha. After respectfully greeting Him, they asked the Buddha: "Venerable Sir, at what time does what is called cold appear?"
