A wise old man asked a sad young man to put a handful of salt in a glass of water and drink. “How does it taste?” asked the Master. “Bad” said the apprentice. The Master smiled and asked the young man to take another handful of salt and toss it in a lake. The two walked in silence to the lake, and the young man threw the salt in. Then the wise man said, "Drink some of the water from the lake.”
As the water ran down the young man's chin, the old man asked, "And now, how does it taste?" “Very good!” said the apprentice. "Do you taste the salt?" asked the Sage. “No!” exclaimed the apprentice. The wise man then sat down next to the young man and said, "When you feel pain, increase your sense of everything in your life, and give more value to what you have than to what you have lost.”
Pain is inevitable, but the suffering (the emphasis and priority you spend on pain) is optional. Thus, the end of suffering is to stop being a glass and to become a lake.
Each time I feel pain today, I will think of five things for which I am grateful. I will thus make it my practice to emphasize what I have than what I lack.
