Intention
Most people would argue that all you need to accomplish large Feats of Strength is believe in yourself. Well, I would argue, that's incorrect. I feel like intention is a better word to explain the way I accomplished these powers when I was younger and just started to LD.

Intention:
1. A course of action that one intends to follow.
2.a. An aim that guides action; an objective.


Much like the way mantras work, you have an intent. You have an aim, or a goal, that you want to achieve, and you intend to achieve it.
What is your guy's opinion on this?
I would suggest that all of you read
