Personally I prefer to activate the whole book in one go, even a big 1000 page technical book I am activating at the moment.
I superead at about 2 seconds a page or less.
I keep doing this over and over and over, until I feel the need to dip.
So far I have superead my book and 15 times, and not ocne have a felt the need to dip.
When it happens, it happens, I will not force it.
There is no conscious decision making...
... I only go with what feels right.
The only conscious act is to reaffirm my purpose now and again.
Reading like this, truly living and being in touch with who you are, the essence of your being is so awesome it has to be experienced.
If you don't let go and experience it, then you're betraying your soul.
