Dualistic thinking Options

Dualistic thinking is very relevant to people following spiritual paths of any kind, since it involves believers who claim to see and experience another existence and others who having not experienced anything they would describe as other-worldy, disregard these claims and it therefore divides people into two camps.

The language used is also a form of dualism as it separates entities into good and bad and places into discrete areas thus: Heaven and Hell.

Is dualistic thinking useful and a good way of hanging ideas on hooks for further exploration or does it lead to extremes of thought that lack balance and settle people into positions that are hard to find their way out of?

I'll make it simple to know what we are discussing...
Sabazel are you saying that Dualistic Thinking as a whole is something you don't practice or the Classification of Good vs. Evil? Is it only this or Dualist thought as a whole?
