I do not love you as if you were salt-rose, or topaz, or the arrow of carnations the fire shoots off. I love you as certain dark things are to be loved, in secret, between the shadow and the soul. I love you as the plant that never blooms but carries in itself the light of hidden flowers; thanks to your love a certain solid fragrance, risen from the earth, lives darkly in my body. I love you without knowing how, or when, or from where. I love you straightforwardly, without complexities or pride; so I love you because I know no other way than this: where I does not exist, nor you, so close that your hand on my chest is my hand, so close that your eyes close as I fall asleep.

Do not stand By my grave, and weep. I am not there, I do not sleep— I am the thousand winds that blow I am the diamond glints in snow I am the sunlight on ripened grain, I am the gentle, autumn rain. As you awake with morning’s hush, I am the swift, up-flinging rush Of quiet birds in circling flight, I am the day transcending night. Do not stand By my grave, and cry— I am not there, I did not die. - Unknown Author

Have you ever considered Greg Goode's very excellent books on non duality? I have read most of the books in your list, a very good list btw. I always recommend newbies read Perfect Brilliant Stillness by David Carse and for something a little more weighty I recommend "I" is a door by Philip Renard which is an outstanding blend of Advaita pointings. After some time seeking I realized I needed a path and for the most part I was drawn to Direct Path teachings and finally Dzogchen but there are doors everywhere you look. ;)
