Hi Alea.....
Yes dualism is everywhere,in everything......BUT
dualism is an illusion,is the illusion.
Once you stop decoding from your left hemisphere,
dualism simply vanishes.....
Fear,ego,good from evil,right from wrong,judgement,
etc all disappear once the left hemisphere stops decoding "reality"....it is merely an illusion.
In fact your ability to participate in the illusion
such as see in 3D space,color,control your body's
muscles,language,mathematics also disappear when
the left hemisphere stops decoding it...
Here's a free copy PDF of Jill's short book that
goes deeper into her experience.....the chapter
on left mind v's right mind is very illuminating.
