Buddha taught that nothing is lost in the universe, that every is in a constant state of change and that there is cause-and-effect in everything. "Seek the Truth" he taught:
"Three things cannot be long hidden: the sun, the moon, and the truth".
I guess we all strive for a bit of Buddha's
wisdom. Maybe that's why icons and statues of Buddha have become a reminder, a decoration even for many who are not Buddhist. It's cool to be wise.
