English to Arabic Other Other Explanation of text

Hello,

Please find the text in question on this link:

https://books.google.com.sa/books?id=AhOzCwAAQBAJ&pg=PA191&l...


My question:

I need help understanding what the writer is referring to when she says
"when you look to art for your salvation"

and also who is possibly referring to when she says:
"like your oldest, dearest friend" since it is not clear enough for me, and maybe someone can help explain this further to me.


Thanks!
