The following is a translation from the Breslover website "Azamra," available at: http://www.azamra.org/sing.shtml
Empowerment through good points
Rabbi Nachman of Breslov's teaching of AZAMRA (Likutey Moharan I:282)
Azamra l'Elokai be-odee!
"I will sing to my God as long as I live!" (Psalm 146:2).
You must also find the good in yourself. A fundamental principle in life is that you should always try to keep happy and steer well away from depression. When you start looking deep inside yourself, you may think you have no good in you at all. You may feel you are full of evil, and the negative voice inside you tries to make you depressed. Don't let yourself fall into depression. Search until you find some little good in you. How could it be that you never did anything good in your whole life?
In just the same way you must carry on searching until you find another good point. Even if you feel that this good point is also full of flaws, you must still search for some good in it. And so you must continue finding more and more good points. This is how songs are made.
And know that the one who can create these melodies by finding the good points in every Jew, even the worst, is fitted to be the prayer leader. The leader of the communal prayers must represent the whole congregation. He must find and gather all the good points in each of the worshippers. All these good points must be joined together in him so that when he stands before God in prayer he comes with the power of all this good. The prayer leader must have the power to attract all this good and gather together all the good points so that they are joined together in him.
And know that every generation has its shepherd, who is the Moses of that generation. For Moses was "the faithful shepherd". This shepherd makes a sanctuary. And know that little schoolchildren receive the undefiled breath of their mouths from this sanctuary.
