Joy is the Radiant Countenance! Joy is Truth! Joy is Emuna (Faith)!
Try to be as happy as you possibly can. Search for your good points in order to make yourself happy.
Hearing the music of one who is truly in awe of God, can help you be happy.
Music and joy can help you pour out your words like water before God. (Creating within yourself a state of constant happiness is the key to achieving true meditation and true prayer.)
A person who is always happy, succeeds.
