This study compared subjective experiences and EEG patterns in 37 subjects when listening to live Vedic recitation and when practicing Transcendental Meditation (TM). Content analysis of experiences when listening to Vedic recitation yielded three higher-order code. Experiences during Vedic recitation were: (1) deeper than during TM practice; (2) experienced as an inner process; and (3) characterized by lively silence. EEG patterns support these higher-order codes. Theta2 and alpha1 frontal, parietal, and frontal-parietal coherence were significantly higher when listening to Vedic recitation, than during TM practice. Theta2 coherence is seen when attending to internal mental processes. Higher theta2 coherence supports subjects' descriptions that the Vedic recitations were "not external sounds but internal vibrations." Alpha1 coherence is reported during pure consciousness experiences during TM practice. Higher alpha1 coherence supports subjects' descriptions that they "experienced a depth of experience, rarely experienced even during deep TM practice." These data support the utility of listening to Vedic recitation to culture deep inner experiences.
本研究比较了37名受试者在聆听现场吠陀吟诵和练习超觉静坐（TM）时的主观体验和脑电图模式。对聆听吠陀吟诵时的体验进行内容分析得出了三个高阶编码。吠陀吟诵期间的体验为：（1）比超觉静坐练习期间更深刻；（2）体验为一种内在过程；（3）以生动的寂静为特征。脑电图模式支持这些高阶编码。聆听吠陀吟诵时，额叶、顶叶以及额顶叶的θ2和α1相干性显著高于超觉静坐练习期间。关注内部心理过程时会出现θ2相干性增强。更高的θ2相干性支持了受试者关于吠陀吟诵是“非外部声音而是内部振动”的描述。超觉静坐练习期间的纯粹意识体验过程中会出现α1相干性增强。更高的α1相干性支持了受试者关于他们“体验到一种深度的体验，即使在深度超觉静坐练习期间也很少体验到”的描述。这些数据支持了聆听吠陀吟诵对于培养深度内在体验的效用。
