This is a basic exercise of imagination. This will later make all other exercises easier.
1. Find a peaceful place where you can be alone.
2. Close your eyes, breath deeply (observe your breathing, do not command it) and relax (you can breath deep 5 times or 15, it's up to you, you know when you are relaxed).
3. Think of an object you have seen today (glass of milk, rose, tree, anything simple)
4. Hold your focus on this object for 5 minutes. See the different changes of color in it, the shape, the texture, the edges, the beauty.
5. Repeat with other objects.
Practise makes this talent grow, eventually you can make the object move, glow, you can see it's energy.
