The brothers chose different thoughts regarding the identical experience theyve been in. One took the fact that their father was a drunk as an example for him to imitate; thus, making him one too. In contrast, the other brother thought the same idea as something not to be mimicked, making him doing the opposite thing until he became successful. Those thoughts over the years shaped the circumstances where they are now. Whatever viewpoint they had about the situation was reflected on how they are doing now.
In other words, whatever there is in our mind can be fully and precisely reflected through our actions. It is due to the process where thinking creates images in our mind. These images, in turn, will control feelings like joy or sadness. Such feelings will cause us to do actions on how we would deal with each one of them. And lastly, these actions shall create results. Therefore, the mind, particularly thinking, implies reflection and creation of results. This is simplified through the very common clich: You are what you think of.
Unbiased towards any Impression
Whenever we look at the outside world, or just any of the things it consists of, we tend to have a very strong impression of its substantiality. What we probably don't realize is that the strong impression is merely our own mind's interpretation of what it sees. We think that the strong, solid reality really exists outside, and when we look within ourselves, perhaps we feel empty. This is a common misconception among people. The wrong mental attitude that fails to realize that the strong impression that appears to truly exist outside of us is actually projected by our own mind. Everything we experience feelings, sensations, even shapes and colors comes from our minds.
