This wooden marker is also located in the Soquel Cemetery in Soquel, CA. The carving is in Russian and is pronounced, Gospodi Xranii, and means Oh Lord protect.
Russian Orthodox funerals are possibly the most achingly beautiful and comforting services one could ever wish to attend. Below is a sample of a cappella funeral music from the Memory Eternal (Vechnaya pamyat) piece that is typically the last part of the service. Makes the hair stand up on my neck every time I hear it.
If you like a cappella, turn up the volume toward the end to really get an appreciation of the tremendous power exhibited by the bass section.
