What to read after Bnei Baruch Kabbalah Official Songbook?

As the language of music is abstract, the spiritual sensations of Kabbalists are expressed by music that may be partially perceived by all. Kabbalistic music expresses two conditions of the Kabbalists: an aspiration to sense the Spiritual Realm, and an aspiration to merge with the Creator in the joyful sensation of total perfection. The music bathes the listener in a wondrous light. There is no need to know anything about it before listening to it, since it is wordless. Yet its affect on the heart is direct and swift, due to the intricate connection between our souls and the roots of the notes. Hearing these melodies over and over again allows the listener to feel the music penetrating deep within the soul, completely unobstructed.
