You cannot learn nonattachment without experiencing attachment.
So, I decided to deeply involve and deelpy attach to something or someone before I practice non-attachment.
Yes, I will experience great deal of pain and suffering by attaching to something or someone but if i don't attach because I am AFRAID not being able to do non-attachment, ultimately I am doing saomething -attaching to non-attachment.
If I decided not to do because of fear of pain, then I am attaching to avoding to my fear.
So, first I have to accept that I am deeply attaching to someone or something. Then, when it crushes, I will learn about non-attachment.
I rather choose to be shredded by my pain than avoiding to face my pain.
