The authors said that these findings shed light on the common
mistake of lumping meditations together.
"Meditations differ in both their ingredients and their effects,
just as medicines do, so lumping them all together as 'essentially
the same' is simply a mistake,' Dr. Shear said.
Zzzzz.
"Other relaxation techniques have led
to the same EEG profile, and studies that
employed counter-balanced control relaxation
conditions consistently found a lack
of alpha power increases or even decreases
when comparing relaxation or hypnosis to
TM meditation (Morse et al., 1977; Tebecis,
1975; Warrenburg, Pagano, Woods, &
Hlastala, 1980). Similarly, the initial claim
that TM produces a unique state of consciousness
different from sleep has been
refuted by several EEG meditation studies
that reported sleep-like stages during this
technique with increased alpha and then
theta power (Pagano, Rose, Stivers, & Warrenburg,
1976; Younger, Adriance, & Berger,
1975)."
