[FairfieldLife] TM claims "quite premature"

[Vaj]

To summarize, alpha global increases and alpha coherence mostly over  
frontal
electrodes are associated with TM practice when meditating compared  
to baseline
(Morse, Martin, Furst, & Dubin, 1977). This global alpha increase is  
similar to other
relaxation techniques. The passive absorption during the recitation  
of the mantra, as
practiced in this technique, produces a brain pattern that suggests a  
decrease of
processing of sensory or motor information and of mental activity in  
general. Because
alpha rhythms are ubiquitous and functionally non-specific, the claim  
that alpha
oscillations and alpha coherence are desirable or are linked to an  
original and higher
state of consciousness seem quite premature.
