If you do not know what the pleasure of doing a volunteer work is about, just Do IT! Nothing in the world feels better than this feeling.
When you wander out in the streets in the heat of the sun, when you knock at the door of every next house, when you ask every passerby for some money, when every one ignores , when every one blames, but you keep on ignoring, you keep on absorbing every painful blow, and you never lose hope, you never stop – because you know the cause, the cause of helping the suffering ones and you are totally and truly dedicated to it. And when you know that your cause is the noblest of all, the pleasure you get from it is unmatchable.
When you engage yourself in a noble deed, God is always with you, He is always there to help you and He never leaves your company until or unless you end your effort. And when you know that the company you have is the best of all, the pleasure you get from it is unmatchable.
And at the end of day when you prepare to sleep, you feel proud of yourself that this day was a great day and you earned most of it in form of good deeds. The soothing pleasure you experience that day on the bed is the most comforting of the comforts you ever experience in your whole life.
