I think that what Mr. Scheele is refering to is getting into the alpha state with a single breath. This is easily possible once you learn how to coordinate relaxation of the mind and body. If you know how to anchor the sensation of state, you can then trigger it anytime that you need to. The Silva Method uses the "three finger technique" to achieve this by entering a deep alpha state and then telling themselves "whenenver I touch the tips of my thumb and first two fingers together like this I am in alpha". After a few times doing this, the action becomes linked with the desired state and Presto! You're there! Many also trigger the state just by recreating the sensations that they associate with alpha.
