Thanks! I took that picture at my sister's and BIL's wedding. On the left is my sister's hand and the right is my BIL's hand. My mom is pouring sacred water on their joined hands to bless their union.
To be honest, beyond that, I'm not sure what else is going on! LOL I'll try to find out more, if you're interested. Actually I have an English explanation of the whole ceremony from my own wedding I used to have up on a website a long, long time ago. :-D
