An important reason for the discrepant findings in different electroencephalographic studies of meditation seems to be the fact that meditation is not a single psychological or physiological state. Visual and quantitative analysis of the 192 channel EEG recordings of twelve experienced practitioners of Vihangam yoga who claimed perception of an inner light through out their meditation practice was carried out before, during and after meditation.
Meditation is not a single psychological or physiological state. There are different kinds of meditation and equally varying states through which one might pass during meditation practice. The efforts to find the electrophysiological correlates of meditation have increased tremendously in the last 50 years (1). However, the results from different studies have been quite conflicting (1,2,3). An important reason for this seems to be the variable nature of the experiences associated with meditation.Perhaps different studies have tapped the electrophysiological correlates of different states of meditation. It thus seems pertinent to perform state-specific investigations rather than exploring a meditative practice as a whole. Also, there is dearth of studies using dense array EEG to get a better spatial resolution of the electroencephalographic changes during meditation. With this idea in mind, we conducted a 192 channel EEG study of the inner light perception state during meditation.
