"As people involved with magic already know, magic is all about imagination, symbolism, visualization and willpower. If You imagine a thing happening in Your head, You will make it happen - that is if Your willpower is strong enough, or if You possess enough "spiritual power". If an object symbolizes a certain power, it becomes that power. That is why our forefathers carved runes into rocks and pieces of wood, because the runes symbolized certain powers. That is why winter and summer solstice and the equinoxes are so important, because they symbolize special events, that are described in our mythology. That is why we originally began to wear jewellery, because the different metals or stones symbolized different powers in the universe.
Burzum was supposed to be such a symbol. Burzum was an attempt to create (or "recreate" if You like) an imaginary past, a world of fantasy - that in turn was based on our Pagan past. Burzum in itself was a spell. The songs were spells and the albums were arranged in a special way, to make the spells work."
