When you see through a coloured glass, the world looks as if it is painted with that particular color. If you look through a red glas, the world is red. If you look through a greed glass, the world is green.
Many of us wear some or other colored glasses all the time. We look thorugh the glass of our own experience, opinionsm point of views and prejudices.
We look at others through the glass of our own customs and rituals and habits.
The moment we start understanding that probably these are the glasses that we wear and the world need not be the color it looks like having it, we are liberated.
