The Great Gatsby, high intention

Could you please tell me if in this excerpt from the first chapter of The Great Gatsby the word "high" means "noble", "elevated" or "firm" and if the word "shining" means "extraordinary", "conspicuous":

I bought a dozen volumes on banking and credit and investment securities (...) promising to unfold the shining secrets that only Midas and Morgan and Maecenas knew. And I had the high intention of reading many other books besides.

Thank you.
