It is not that the self ego causes dualism.. ego is not an entity, it is merely a process of identification and is fundamentally empty.
The judgment, division and separation is itself the workings of the sense of self, or the ego. The most fundamental duality is the duality of subject and object. This is because when there is a separate self or a subject, we see an 'other than' -- we see objects separate from ourselves as having inherent existence, and then we divide them into oppositions and dualities... i.e 'good and bad', 'tall and short', 'big and small', from there we grow dualistic attraction and aversion (i.e greed and hatred) to things or people, thus forming the 3 poisons, greed, hatred, ignorance.
Our Mind is simply like a mirror that is one with all that is arising moment to moment. It simply reflects and embrace fully, because it is not separate from, moment to moment arising. All reflections are in essence empty of any inherent existence, but when we fall into duality, we choose this over that, we separate what is whole into dualities and opposition.

I wrote,
...Which is also why my Taiwanese teacher always say, Mind, Buddha, Sentient Beings are not three different things. Chu Shi Jian Fa (other-worldly dharmas) and Shi Jian Fa (worldly dharmas) are all empty in essence, all not separated from arising of causes and conditions and impermanent... therefore there is no purer states than everything else... therefore there is no choosing (zhu fa ping deng) for they are all empty and equal.
Like Thusness said, Like Zhuang Tze "zhou wang", allow the ten thousands things to flow in you and move heaven and earth with this non-preference. and "The problem is we choose, but all is really it. There is nothing to choose."...Also when we talk about 'Non-Duality', we must also be able to discriminate what are the different forms of non-duality because when people talk about non-duality, it can actually mean many different things.
Non-Duality of Subject and Object is the sort of insight of enlightenment that there is no observer apart from the observed. It is seeing through the illusion of there being an Agent, Self, Watcher of phenomena, Doer of deeds, Thinker of thoughts...
Instead, deeds are done without a doer, hearing hears without a hearer, thought thinks without thinker, that all there is is simply the obvious self-luminous/self-knowing spontaneously arising appearances of "life" (which is not 'something' but an utterly transient-conditioned-arising-process of the 5 skhandas) with no one/no center living or experiencing it, and which there is no one/no self that could even escape from it even if they wanted to... all there is is simply an expression, a manifestation of our True Mind, our Buddha Nature, etc (pick a name, there is countless) which is essentially luminous-emptiness.
There is also another form of non-duality which is the non-duality of process, though we must be able to distinguish that the non-duality of subject-object is different from this non-duality. This is the non-duality of Yin and Yang (including 'gain and loss', 'health and sickness', 'wealth and poverty', etc), which are in constant change and interaction, and therefore these polarities certainly isnÂ’t opposites; these extremities are themselves a single whole. It is only due to our power to abstract that we hold onto dualistic views.
The non-duality of process is like what Thusness said about attachment leading to non-attachment, as well as what Eckhart Tolle said which I posted before:
