But when I am "reading" like this, I usually develop a habit that read the passage word by word sometimes. Or I could just see blurr image, it is still alright...?
Turn the book over it's reminds you not to start reading. Also say the chant and keep turning the pages. If you find yourself pulled into reading turn the pages faster.
Yes; it is all right if you just see the blurred image. Your other than conscious mind is still processing the information even though the information on the page is blurred. Photoread4me
