Do you know why it is important to see yourself as a servant of light, as a servant for the higher good when being on a spiritual path?
Because whatever spiritual path you take, may it be the path of western mysteries, kabbalah, witchcraft, paganism, buddhism, christianity or another old tradition or religion, it gives you so much power that you may want to use it to manipulate and play with other peoples lifes. This power you get, could easily take control over you without you knowing. Making you looking down on others and thus making you become arrogant.
Humbleness is the virtue of the truly powerful.
