@slowwalker,
Wow it's wonderful! They crafted these statue of Lord Buddha on a rock so brilliantly! One other thing that I was curious is, similar type of carved Buddha statue is at my country.
It's at Buduruwagala! here I am attaching it with this comment! Did you notice similarities! I wish you might visit my country and I can assure you can see lots of Craved Buddha statue here as well! Thanks for sharing such wonderful and rare experiences with us!

Cheers~
