Don't forget; Volition is not only a free ride into Yama's mouth from the nidana link called volition; But also a skandha... kinda like the Monopoly card that says: Do not pass go, Do not collect two hundred dollars, Go straight to jail.
Best to think of the Ox Herding pictures when getting the ol' mental elephant out of the mud. The Buddha just sat there as his "friend" lamented about what his "family" was doing to his house not getting a clear drink or bath... not seeing himself; Being the only one churning the great ocean and thrashing about in such attachment, in that very moment of recollection.
Breath is not an easy thing to hold as meditation; without noticing it? You may have not breathed in forty kalpas, and on noticing it? Pow right in the kisser.
Tactile sensation is an easier one; and breath thought of as a last resort... Zen meditation posture where the tips of the thumbs are lightly touching is my suggestion as a better grip... breath arouses different states of mind to notice arising and passing away... basically in seeing the rising and falling of the three poisons. As soon as one releases all three? Who knows how long has passed... an aeon in a moment. First glimpse of Nirvana... Which ever of the three attaches greed, hate or delusion at that bubble bursting? Never you mind as all three have returned like a council of Anagamin expecting you to be their new sacrificial lord and savior; to wallow and thrash about in their greed craving and desire.
Oh and you will thinking you have attained something other than letting go is an even worse attachment; as it only mires one in delusion. Eventually you'll come out on top of that animal be it greed, be it hate, or be it delusion. Keep on sitting and they will just eat each other out of house and home.
Jhana states and siddhi/riddhi are their biggest attachment and failings on the path... having grasped at one feeling and equating it to nirvana/nibbana thinking it attainment? Yours, mine, and countless others too.
Chasing jhana states and the siddhi/riddhi is the downfall of every meditator at some point.
After that point; One sees the truth of: "No god no brahma can be said to be the maker of all of this."
I have no problem saying that; that book is poison on the path to Buddhahood/Dakinihood from direct experience of it as a path and result. That quote above; Is really the only thing to be learned from it.
