Results: Meditators as a group showed significant increase in Alfa actitivity in occipital region of frequency of 8 Hz and decrease of - activity in parietal region compared to controls. Diastolic blood pressure, heart rate and respiratory rate showed a significant reduction before and during meditation among study subjects compared to controls.
