I'm glad you didn't pull it to pieces (maybe cos of its rather experimental or pseudo tech style), haha.
Me too wasn't expecting this cute driving role of the bass line while assembling the tune.

Btw. loving such songs with a mystical or even cabalistic touch. The term Leth (in the title) is an expression from paranormal science - Leth is a mechanism to neutralize outer influences (which could attack on different existence levels) by transforming them and using their energy to build alternative structures which lead to lightful dimensions.
In other words: suffering and pain are relative, even though they're felt as negative and paralyzing elements in human life, they can/should be taken as pure sober information to help us constructing and improving our philosophy. So called bad things are but illusions (as good things are as well), based on our brain's interpretation of the world. Just like the death of a child in a dream, none of the things happening around us have any meaning in itself - instead it's only our point of view which determines the quality of our life.
