Thanks for sharing! This has really peaked my intrest.
Although I have not personally tried passage meditation, I definitely understand where you are coming from with distracting thoughts floating around your head. As you said this is the nature of meditation at first and of course the goal is to do away with these.
I have done a bit of research on Easwaran and passage meditation and have a few thoughts. Although it could be helpful, I believe I would find the longer passages distracting and harder to maintain my attention. If they are well memorized then maybe it could work but I personally believe mantras would be more effective. I use these a lot and there are hundreds of thousands of them. It is a similar concept but just shorter phrases. I find this very effective because anytime I do get distracted I can simply start back at the beginning of the mantra and re-center myself. I think this is a similar idea for what you are doing.
Again this is just personal speculation and I am going to be trying some of this passage meditation very soon. (tonight)
“How long will this last, this delicious feeling of being alive, of having penetrated the veil which hides beauty and the wonders of celestial vistas? It doesn't matter, as there can be nothing but gratitude for even a glimpse of what exists for those who can become open to it.”
