When we think about something for long time, even at a time when we don't actively think about the issue, subconsciously the thought arises and sometime it provides nice answers. This indicates the importance of mindfulness. When we are mindful about any problem, let us deeply think on the matter time and time again. Even if we can not arrive at a decision, let us wait. After certain time, our subconscious brain triggers the thoughts and it pops up unwillingly. This is a wonderful thing to experience.
