Urbanization in past few decades has grabbed a huge amount of our agricultural land leading towards various climatic problems as well as endangering our sustainability. Thereby, utilizing the underground earth space instead of using land mass and its resources will transform the lifestyle and will sustain our livelihood. Civilizing and urbanizing underground ecologically enables our sustainability and will contribute to protect the natural resources for future.  The better utilization of land and sustainable use of earth space will play a vital role to protect our natural resources and maintaining our sustainability. As various research and study shows our planet can sustain up to 11 billion population and we are currently 7.6 billion right now, which is considered to reach deadline till the end of this century. Therefore, utilizing underground earth space will provide enough space for building sector and agriculture sector and will serve the purpose in both ways. Thus, it is quite important to clear the way for sustainable pattern of underground civilization.

The scientific community has long been interested in mantras and meditation. However, very little study has been done on specific mantras such as AUM. The major goal of this bibliometric study is to aid AUM meditation research by finding all connected publications and subject coverage, as well as uncovering historical trends, active research domains, prominent journals, authors, organizations, and nations, as well as linkages between them. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria were used to search the Dimensions.ai database for AUM-related articles. VOS-viewer was utilized to reveal emergent trends and transitory patterns in the literature, as well as to demonstrate international collaboration, organizational coupling, and co-cited author networks. After a thorough screening and extensive article reading, fifty studies were chosen for the study. According to the findings, India produced the majority of data. More than half (62%) of the publications were in the field of “Medical and Health”, and about one-sixth (16%) were in “Psychology and Cognitive Sciences”. Based on Publications “The International Journal of Yoga” has the most publications (26.66%) and citations (40.87%). The strongest linkages are found in “Venkatasubramanian, Ganesan (952)”, “India (101)”, and “National Institute of Mental Health and Neurosciences (192)”. This bibliometric analysis synthesized and illustrated 48 years of AUM meditation research, indicating key highlights, and rising trends. The findings of the study contribute to the creation of a platform for future research in the field of AUM meditation.

Yoga is being used as a mind-body complementary and alternative medicine intervention to help people with specific physical and mental health issues. In terms of the study area, yoga is an attractive field with various scopes and also contributes to scientific research. In this context, the current study is simply aimed at fully identifying the function of yoga intervention on students in academic institutions, as well as evaluating the available research data in this sector. A search query of relevant keywords was strategized and optimized to extract the information of research articles published from 1992 to 2021 from the “Dimention.ai” database. The obtained dataset was analyzed using PRISMA to evaluate the effect of interventions. The results indicate that the United States has published the maximum number of scholarly publications (553) among all countries. If we talk about organisation Swami Vivekananda Yoga Anusandhana Samsthana from India has published the most of the articles (39) in the field of yoga education. The journal “Mindfulness” (14) and author “Shirley Telles” (14) from the “Patanjali Research Foundation-India” have published the highest scholarly articles. In the bibliometric coupling of distinct clusters, the strongest link strengths among the authors, countries, and organizations were observed for “Khalsa, Satbir S.” (4915), “The United States” (47347), and “Harvard University” (8485), respectively. The current study indicated that yoga education studies have a huge spectrum of publications. Moreover, these bibliometric indicators provide significant endpoints to evaluate research output productivity and quality. The study's findings aid in developing a framework for additional research in the field of yoga and its usage in the academic environment.
