Ordinarily, when we talk or go for a walk, our mind is filled with a whole range of distractions. When we cannot concentrate or stay focused, it is difficult for wisdom to arise. It is only after subduing the mind, when it becomes clearer and sharper, that our thinking is more focused and more effective in problem solving. This includes problems connected with running a business and earning money.
Actually, many of the exciting discoveries made by scientists and philosophers in the past came during meditation and in their dreams. In no case did it happen when the mind was agitated or in states of discursiveness.
