The PubMed biomedical literature database reports a spurt in #Yoga research in recent years but > 90% of it relates yoga to health conditions.
In a 2014 article in the International Journal of Yoga (In search of yoga: Research trends in a western medical database) Marcy C McCall reports that while the first recorded yoga article in western medical research dates to 1948, authored by E. Abegg, there has been a surge in academic interest post-2007, with an average of 200 articles being added every year in recent times. The article concludes by stating, ‘Systematic reviews and yoga trials are increasing, indicating a potential increase in quality of evidence. Three conditions show consistently high correlations with yoga research: stress/anxiety, pain, and depression. A significant rise in the number of cancer publications suggests an area of emerging research.’
Yoga has been described ‘as a safe and effective intervention to increase strength, flexibility and balance, and treatment for high blood pressure, heart disease, aches and pains, depression, stress, and potentially asthma’ by the National Institutes of Health, USA, and by the National Health Services, UK. It is less known that yoga seeks to align individual health with social health, which is in line with WHO’s definition: ‘Good health is a state of complete physical, social and mental well-being, and not merely the absence of disease or infirmity. Health is a resource for everyday life, not the object of living, and is a positive concept emphasizing social and personal resources as well as physical capabilities.’
The Bhagavad Gita (verses 5.23 and verses 6.20 to 25) tells us that yoga helps us reconcile our aspirations with the outcomes, tolerate agitations that arise from desire, and recognise that expectations and disappointments are par for the course for sentient beings as long as they live.
The path of Yoga suggested by the Gita provides for the inescapable reality of expectations. It also grants that it is natural to feel frustrated when these expectations are not met. However, it counsels us to show forbearance in the face of such disappointments. Yoga, says the Gita, helps us cultivate an endurance to the psychological pain akin to the fortitude with which we learn to bear physical pain.
