The characters on the left and right are basically a buddhist blessing ie: may god be with you, amen or something along those lines. don't remember the exact translation at this moment.
The text at the top is the name of a temple, the name also escapes me right now. The only thing left is the translate the Thai text on the bottom before I commit it to my arm.
The monkey in the middle is a depiction of the character Sun Wukong. This story is also a loose basis for the Dragon Ball series, which I also happen to be a bit of a nerd for. win. Going on my upper right arm.
