He raises a glass of water and asks the audience
"How heavy do you think this glass of water is?"
"It depends on how long you hold it."
"If I hold it for a minute, it is Ok."
"If I hold it for an hour, I will have an ache in my right arm."
"If I hold it for a day, you will have to call an ambulance."
"It is the exact same weight, but the longer I hold it, the heavier it becomes"
If we carry our burdens all the time, sooner or later, we will not be able to carry on, the burden becoming increasingly heavier.
"What you have to do is to put the glass down, rest for a while before holding it up again."
We have to put down the burden periodically, so that we can be refreshed and are able to carry on. When you return home from work, put the burden of work down. Don't carry it into your home. You can pick it up tomorrow. So Rest and Relax.
