There is a very special connection between orthodox and icons.
For the faithful an icon is a window connecting two worlds that are visible and invisible.
An icon is holy by the image depicted and the name of it
Every home has a special icon that has been part of the family for a very long time, even centuries.
When in orthodox church go and pray in front of holy icons but even talk to the icon.
Please never disturb them, interrupt them, or pass between them.
If it's a small church please wait outside till the person has finished.
