in_progress, I too believe that what we read has effects on the energy. When my spiritual awakening happened, I was reading the book 'Autobiography of a Yogi' by Paramahansa Yogananda, I still haven't finished it, because every time I pick it up the energies are felt a bit more.

I think in general, whenever you think of Kundalini you will feel it flowing, just an impression I have.
When my energy is really fired up, I feel it like I have a spear inserted along in my spine, that goes out from the top of my head, that has happened 4-5 times and lasted about 30 min.
