When Marpa, the great Tibetan meditation master and teacher of Milarepa, lost his son he wept bitterly. One of his pupils came up to him and asked: “Master, why are you weeping? You teach us that death is an illusion.” And Marpa said: “Death is an illusion. And the death of a child is an even
greater illusion.”
Marpa was weeping. A student asked him why.
“My child has died and I am sad.”
‘But Marpa,” the student respectfully said, “you have taught us that all in this world is an illusion.”
“Yes,” said Marpa, “but some illusions are more important then others.”
Someone asked Marpa, "Marpa, how are you now?" Marpa said, "As
miserable as before."
The man was bewildered. He said, "As miserable as before?"
But Marpa laughed. He said, "Yes, but with a difference, and the
difference is that now the misery is voluntary. Sometimes, just for
a taste of the world, I move outwards, but now I am the master. Any
moment I can go inwards, and it is good to move in the polarities.
Then one remains alive. I can move!" Marpa said, "I can move now.
Sometimes I move in the miseries, but now the miseries are not
something which happen to me. I happen to them and I remain
untouched."
I love Marpa's teaching.
