Meditation is generally described as being in the present moment or being alert in the present moment, instead of constantly struggling to change or to become. Meditation is an essential part of Yoga philosophy and the seventh limb of Astanga Yoga described by sage Patanjali in the ancient text Patanjali Yoga Sutra. Yoga including meditation, is an ancient technique invented to unite the individual consciousness with the universal consciousness, however, scientific studies have demonstrated the vast health advantages associated with it. Mindfulness as a non-judgmental awareness of the present-moment is also a part of yoga philosophy, however, most of the mindfulness practices those are being practiced in modern days are also rooted in Buddhist philosophy. Some well-known meditation techniques are Buddhist meditations, Hindu meditations, Chinese meditations, Christian meditation, Islamic meditations, Guided meditations etc. Meditation influences brain systems involved in attention, awareness, memory, sensory integration, emotion regulation, and higher-order cognitive functions. Meditation has also been found to be very effective in relieving stress, regulating emotions and promoting mental health. A significant increase in grey matter volume was found in the meditators as compared to non-meditators. The larger grey matter volume overall, and with regional enlargement in several right hemispheric cortical and subcortical brain regions are associated with sustained attention, self-control, compassion and interoceptive perception. Several functional neuroimaging studies showed that some brain regions are recruited consistently across different meditation techniques including insula, pre/supplementary motor cortices, dorsal anterior cingulate cortex, and frontopolar cortex.
