After the feedback on this forum about polarity , I don't think that a lot of people "get it". It probably isn't a good choice for a book for the masses.
A while ago you didn't release your videos about your blogging workshop to not get publically seem as somebody who teaches blogging. If you didn't change that intention, I don't think that you have a reason to start going down that path. If you don't have a problem with being seen that way anymore, there no reason to hold back those videos.
Conscious Business - I don't think that your four year experience is enough, for that topic. If you wanted to write that book, I think you should interview a lot of other people with Conscious Businesses.
That would be a different style of working than most of your blog and your book.
I would also vote like Bruce, for developing your ideas of TLP into more practical day to day applications. Time Management & Productivity from a TLP perspective.
I think that their a lot to gain from developing your ideas of TLP.
Another interesting book might be:
Truth, which would go into even more depth.
The same could also go for Love or Power.
