The Kabbalah lists many blessings that one can attain, and using the light of one who who studies and teaches Kabbalah is extremely meaningful.
Rav Berg founded the Kabbalah Center, and he is considered by his adherents and followers to be a leading Kabbalist and Kabbalah teacher. At Youtube you can see him making the benedictions and doing some singing at a wedding.
I would advise going to Youtube to watch it.
