"Everything is useful, everything you live is important for your development, from the smallest to the biggest thing. Even what you perceive as totally insignificant can be a very important key to your evolution. So, always be attentive to yourself, learn to listen to yourself, learn to look at yourself.
Also learn to look at your brothers; often your brother is the mirror that sends you back your own image which shows you what you really have to work on. Your brother is your teacher, your master, as you are his teacher and master. Each of you gets the picture that resonates with everything that is flawed and you return the same image that will resonate with your own imperfections. So if you want to know what you have to work on, look at your brothers. And if something really bothers you with the one in front of you, know with great certainty that this is what you have to work on. Even if you want to hide it, even if you do not realize it, it is the image sent back to you.
When you no longer see any fault in your brothers, no darkness, when you see your brothers as being perfect, it is then that you begin to achieve perfection and wisdom. But while there is a hint of criticism or judgment, there will still be many reflections returned to you by your brother's mirror."
