The fasting in Ramadan automatically slows down your life and more importantly your thoughts. The decreased energy from fasting means you are less likely to jump from one thought to the next without thoroughly thinking about whether this thought helps you in life. This plays a role in us paying attention to what we are thinking and fixing our thinking process if necessary. Not all our thoughts are productive or positive. The fasting in Ramadan allows you to slow down enough to pay attention to those thoughts that are harmful to our character and overall growth and further pushes us to replace those thoughts with genuine positive ones.
