The teaching monk taught us to visualize any kind of Buddha image we liked. I could do that but got a little indecisive when it came to choosing only one to focus on since I had so many in mind. I could not visualize a crystal ball for I felt that it was impossible to have a crystal clear ball which was normally quite heavy in my stomach. I then decided to go back to Bangkok. However, I did not do so due to the fact that I was astounded by Luang Phaw Dhammajayo's meditation advice carved on the stone in front of the meditation hall,saying that " Can you just only still your mind?"
