How to practise without having aversion towards life? Before I started studying Buddhism I had desire for life and desires for more in life. That eventually led me to inevitable and immense suffering and eventually to Buddhism.
Now as I practise Buddhism and as I study sutta and all I understand that rebirth is something we need to avoid by practising dhamma. We have to end this cycle of Life and Death and eventually suffering. Buddhism is a  soteriological practise and philosophy which guides us out of samsara. Also lot of Buddhist suttas mention suffering as inherent and innate.
Now this has led me to other end of thought spectrum of aversion towards life. As I learnt and understood 'craving for non existance' is also a craving and should be avoided. But how can one think otherwise. Its either I want life or I dont want life and undertake an arduous journey towards Nirvana. How can one not feel aversion towards life if one desires and practises towards Nirvana.
My question is how do I think or train mind to not have either desire or aversion towards life?
Case 57 of the Blue Rock Collection I alone am holy
Case A monastic said to Zhaozhou, &quot;It is said, 'The Great Way is not difficult. It only abhors choice and attachment.' Now, what are
nonchoice and nonattachment?&quot; Zhaozhou said, &quot;I alone am holy
throughout heaven and earth.&quot; The monastic said, &quot;It is still choice
and attachment.&quot; Zhaozhou said, &quot;You country bumpkin! Where are choice
and attachment?&quot; The monastic was speechless.

How much better off we'd all be if we discarded love and hate.  As it says in the Hsin Hsin Ming, &quot;to set up what you like against what you dislike is,&quot; indeed, &quot;the disease of the mind.&quot;  There is a road the runs the valley between the cliffs of this and that, of right and wrong.  It alone is holy throughout heaven and earth.  What is the mind that knows no discrimination?  Where is it found?
Craving and aversion set the world at arm's length.  We can never be fully intimate with the way things really are when we are pushing and pulling on existence.  When we do that, we only know our pushing and pulling.  Instead, let yourself be pulled, allow yourself to be pushed.  Meet both existence and non-existence, samsara and Buddha, enlightenment and non-enlightenment with the same open heart.  That alone is true holiness.
