Thank you.
I think in the end is the pursuit of truth and sometimes it manifests ambiguously, Yin Yang. There is both sides and we don't really know from our perspective, it is so narrow and little. Recognising this without judging and condemning ourselves is a good favour of freedom we can do to our beings and to others. Because it gives us freedom of movement.
Trap ourselves in the good side of the story makes us fight a war constantly and exhaust our efforts. And the result is growing a larger shadow and finally becoming it. Snap to the other side in an outburst.

It is quite difficult to explain, I know this because it happened to me, I've seen it in action. And the thing is when you pay sincere attention, you start to see the manifestations of it in your life. So it begins to be clearer what you need to work on and nurture to create differently. You give to your dark side a place to exist in some order of time, space and action. For example you can become a monster at some sport or in a theatre, pursue your ambitions merciless, fuck banks stack sats, study how to impress and improve and attain power.
 The twofold effect is you get to know your shadow better and you avoid being tricked and manipulated by pricks and evildoers. You know how to identify when people is casting their shadow upon you. When they have double and triple intentions. You see more clearly because it resonates with the parts of you that are there alive at the same frequency.
By killing or damping your own darkness you don't cure the wicked in others. It only makes you vulnerable. 
Paraphrasing McKenna, we just don't know what we don't know and life is stranger than we can suppose. So staying humble and openminded is better 



  

 Sorry for the rant haha!
