The example of parents is the greatest teacher. Parents must stand out as models of happiness to their children.
Adults are the first and foremost teachers of love, peace, truth, tolerance, happiness and spirituality to their children. No school on Earth can ever replace them.
When I was a child, I spoke like a child. When I was an adult, I no longer spoke like a child. When I became old and wise, I spoke again like a child. I wish I had spoken all my life like a child.
