The Sutra Search

You are leaning againt a tree near a lake when you notice something strange in the water.
You walk over to get a better view. Leaning over the water you are suddenly pulled in by a strong force.
When you open you eyes everything looks different and you realise that you've just gone back in time.

Frantically you look around for the porthole so you can go back to your time, but it's gone.
A little man pops up from behind the tree and says, "If you can find my sutra then I will help you get back. I lost it somewhere I can't seem to find it.
Here," he hands you a map, "this is for you. I'm pretty sure that I left the sutra in one of these places.
When you have found it come back here and I will help you get back. I think I might have left it where
King Suddhodana and Queen Maha Maya ruled. You should look their first. Oh well good luck!"

Follow the clues and they will lead you to the sutra.
