Crossing lines can make us feel as if in a different reality.
A small line can make us feel big or small, upright or upended.
When I find a spot that creates an interesting perspective of what is close or far, small or big, I enjoy imagining what will pass there in the next few moments, and where I would like it to pass.
Like in an ambush situation, I breathe deeply, close my eyes and then slowly reopen them, trying to be invisible to other people, like a bird in a tree.
Then, all of a sudden, my thoughts creating reality—what I have imagined, happens.
I have been using this technique for many years, finding it works in many different situations in life.
I encourage you to use it as well.
