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?

by all means, do choose to stop beathing. If you feel you have the choice.
If you can manage to hold your breath until you pass out i would be surprised. Even more so you should realise that it would be against your nature.

There is no dualism in your mind about breathing, you can choose to think in dualistic terms about it. But it will not serve you well.

If you let it be, like you always did, you will see that you breathe quite naturally without making choices.
