The Buddha said, “All fear and anxiety comes from a mind that is untamed”, and, “There’s nothing to fear except your untamed mind.”
If you know how to transform the mind, you can transform fear and anxiety. Once you’ve done that, you can tackle any problem with greater composure, wisdom and insight.
A great Indian master once said:
'If you can do something to solve a problem, then there is no need to worry about it. But if you cannot do anything to solve a problem, then it doesn’t help to worry about it either.'
In both cases, worry is unnecessary. If you are too nervous, too anxious about your problem, then you won’t be able to do anything about it. So the main point is to work with the mind in order to become clear, to understand our emotions better and gain more control. Once mind is transformed, we no longer need to be so deeply influenced by our thoughts and emotions. We realize that our situation is not impossible. In fact, we see it is workable.
