Concepts like fear only exist within a dualistic paradigm. There is no space for fear to exist within non duality - fear of non duality is by it's very nature a fallacy of dual thought to begin with. The symbol 'Wu" or " mu" sums that up in more detail.
"love is the pursuit of the whole "
In my opinion - we experience duality and polarity in order to remmber the true non dual formless nature of ourselves. The animating force behind every person, animal, plant, star, galaxy. All the same unified force expressed in a multi faceted way. To define unity is to acknowlege separation and to experience perceptive separation is to acknowledge the unfolding return to unity /singularity.
It all boils down to the 'I ' of the experience. Beyond the entire experience , the I remains unchanged. The I before any metaphysical decoration. The perceiver of the old I after it takes a conciousness--hammering can have a hard time finding framework for the experience after it has been permanately re-shaped , or even de-shaped.
Sometimes we learn more when we have our ego mind gently dissolved , and sometimes more when it is intensely shattered. Finding the truth and beauty in the latter can be hard but accept it's silent challenge and see it all As a blessing in disguise . An invitation to yourself to uncover more of your self and an invitation to take stock of what builds the self and what thoughts do for ( or against) it.
Universe sometimes has a very tough - love approach to it's curriculum , but at the end of the day it's all love and it's all things .
Integration is such a key and sometimes understated aspect of any inner and outer space exploration. As long as you can identify and work with the tthings you have learnt from it, as apposed to just the psychological trauma,then you're never really at loss...easier said than done of course but the lessons learnt and humility gained will always bloom , if not straight away then at some point sooner or later.
P.S
Check this thread for a more authentic ( less dual
) perecption on duality/non duality.
