Don't dust of your books, you won't find answers there. Books are about
dhamma, they are not Dhamma themselves. And you want to see Dhamma. So instead, dust of your meditation cushion. Go sit down, see what the mind does and relax.
To see that consciousness is inconstant is one of the hardest things, but you can get a little flavor once external senses start to shut down one by one. Eye and nose consciousness (sight and smell) go first. Sounds and the body consciousness can also fade away. Only mind consciousness will be left and it will be silent and focused. Because that awareness is the only thing left, it becomes takes itself as object. For the first time, you are looking really at what's beneath all the other stuff that has occupied the rest of your life. By looking deeper and deeper, you may see that this mind is also empty... And then you come to some understanding through your own insight, which you won't ever find in any book, because you know it can't be put into words.
And take it easy. Be content with what you already know and what you already have.
