If you read the book you know why they would not be able to climb a tree and the tree was described as thin and Katniss was so light compared to the other tributes that she could climb up the skinny branches without breaking them.
SPOILER ALERT (for those of you who haven't read Catching Fire yet) Definitely need to do this to my alarm. But more like "If Jennifer Lawrence can play Katniss, run, & shoot arrows, and still remember lines flawlessly, you can get up"
This is a charging board! It is a simple way to charge up and cleanse your crystals without having to focus on visualisation. Simply put your crystal in the center of a piece of paper, and write around it two categories of words: the things you want to fill your crystal with, and the things you want out of them. Then draw arrows pointing into the crystal for the positives, and away from it for the negatives. This is a visual way to charge/cleanse without having to maintain focus.
