Disciple and Master

After feeling bad experiences earlier night and whole of the day, a disciple was feeling very agitated. A bad day was still haunting him into a cool evening. Not able to calm himself he went to Master.
“Master, Master, why is everybody so bad to me?”, he asked Master
Master raised his eyebrows questioningly.
“The night had been very bad. A moonless night with all stars darkened by dark clouds! There was not a shade of light to see. There were cold gusty winds to accompany this total darkness. It was a night of ghosts dancing all around me. I was not allowed to sleep, not have a moment of peace. Cold night was followed by a very hot day. My well had been dried up and I had to walk a mile to get some water. The sun was so cruel that it kept on scorching my back, my face.”, said the disciple.
Master spread his eyes smilingly.
Getting more agitated by such a smile, the disciple continued, “This isn’t all. On my way back, feeling tired and hungry, I saw a mango tree. I ran to it to get some mangoes, but it had hidden all of them. There was not a single mango that it would offer a hungry, suffering man!”

Master’s smile widened. He said, “Yes, maybe I know that tree. Once I saw traveller there, full of hunger and thirst, lying underneath that tree. I ran towards him, intending to ask him to told on till I get water for him. When I reached him I was surprised. He was smiling and speaking to the tree. He was thanking the tree that it gave him shadow in his last moments. So now he could meet God with cool head and warm heart. I got him water and gave some food that I had. He thanked me, thanked the tree again, got up, bowed to the sun and walked on. He never ceased to smile.”
