Their kind of meditation is so well unspecified.We simply don't know what they did to make an evaluation of, not to say judgement supported by a legal opinion.That website is peculiar, why a person (i.e., Volkov) clearly being not a specialist or even a practitioner of NLP, TM, TA neither of the scientific method etc engages in these worries about potential danger of the things, even theory of which he cannot specify?And why should our attention be brought to it?? We are not practicing 'meditation' here, in Openmeta, are we?
