Outcome Measures
Primary Outcomes (2)
Change in Frontal Midline Theta Power after 6 Months of Daily Meditation Practice
Frontal Midline Theta Power is obtained from an average of 8 electrodes (Fpc, Fc, Cz, Pz, Oz, F7, F8, P7, P8) around the midline in a standard EEG cap and has been proposed as a correlate of meditation success in previous studies. Increased value suggests increased control over the brain's default mode network, suggesting more successful meditation experience.
Measured at Baseline and 6 months
Change in Gamma Slope Index (GSI) after 6 Months of Daily Meditation
GSI is an indicator of the Excitation-Inhibition (E-I) balance in the brain and is computed from the power spectral density slope of oscillatory activity in the brain, taking the low-gamma (40-60Hz) band slope of the Power Spectral Density, and is steeper (more negative) when the E-I balance is tipped towards more inhibition. A higher negative value suggests shift of the brain's excitation/inhibition balance toward more inhibition, indicating a calmer brain.
Measured at Baseline and 6 months
Secondary Outcomes (3)

Study Arms (2)
Wellness and Meditation-Based Intervention
EXPERIMENTALShambhavi Mahamudra Kriya: a multi-component 21-minute meditation that incorporates a combination of different breathing patterns and meditative components.
Control
NO INTERVENTIONControl Group: selected to be age, gender and education level matched with the intervention group and will be asked to continue their daily routine while completing surveys at each timepoint.
Interventions
The intervention is taught at the Inner Engineering program offered by non-profit Isha Foundation as online as well as in-person formats. It incorporates a combination of different breathing patterns and meditative components. The intervention training provides precise, step by step and easy to follow instructions on how to perform this practice. Performed in a seated posture, this is a simple, safe and accessible intervention that requires no previous experience of meditation. The intervention selected for this study was shown to significantly reduce perceived stress, enhance self-reported general well-being, improve positive emotions, mindfulness, sleep, engagement, relationships, and may promote enhanced Heart Rate Variability and Sympathovagal balance.
Eligibility Criteria
You may qualify if:
- Individuals between the ages of 20-65 years.
- Subjects will be required to be able to understand study instructions and provide informed consent.
- Currently residing in Massachusetts.
You may not qualify if:
- Non-English Speaking. (Justification: Meditation and cognitive assessment instruments are not validated in a sufficient range of languages, and the research team lacks polylingual capabilities or the financial resources to hire interpreters for the duration of all proposed assessments.)
- Practicing meditation regularly for the past 6 months (3 or more times per week of practice regularly for the past 6 month).
- History of psychiatric illness such as severe anxiety, severe depression, Schizophrenia or bipolar disorder.
- History of any form of cognitive decline or neurological conditions such as dementia, Parkinson's disease, Alzheimer's disease, Huntington's disease, brain tumors, brain surgery.
- Current use of cognition enhancing drugs
- Current management for chronic pain.
- History (within the last 5 years) of stroke/aneurysm.
- Active history (within the last 5 years) of alcohol or drug abuse (\> 10 drinks per week).
- Current pregnancy or planning to become pregnant in the next 6 months.
- Currently enrolled in another interventional study that could impact the primary outcome, as determined by the PI.
- Educational attainment below high school level or equivalent.
- Significant visual impairment.
- If a woman becomes pregnant during the course of the study and is willing to stay as a subject, MRI will not be conducted.
