Mental and Emotional Benefits

A survey on Shambhavi Kriya practitioners revealed that a year of Shambhavi Mahamudra practice yielded significant mental and emotional benefits. Without requiring any lifestyle changes, practice of Shambhavi has proven to result in better focus, greater joy, happiness and inner peace.

Mental Clarity
Emotional Balance
Energy Levels
Inner Peace
Self Confidence

Brainwave Patterns

A study conducted on Shambhavi practitioners revealed an increase in the most restful brain patterns in comparison with the control group. Shambhavi proved to provide the quality of rest, relaxation, and regeneration that is normally observed in the deepest stages of sleep.
