ABSTRACT The study aimed at investigating the fundamental nature of Shavasana and Supine Meditation, in terms of cellular health, measured through Bio-Phase Angle, energy expenditure, measured through RMR and Emotional Intelligence, measured through a standardized test. In a study with Quasi Experimental Design, having Pre-Post-Follow up Testing sessions, 101 new entrant students of both sexes, age ranging 18-35, from a yoga college, were randomly allocated into three groups namely Shavasana, Meditation and Control, using Xcel Sheet method, with each group having 33 students. Those registering their attendance less than 80 percent and those opting out of the study were excluded from the data analysis. All the three groups were tested for Bio-Phase Angle, RMR and Emotional Intelligence before the start and at the end of the respective interventions, the time duration of each of which was one hour every evening for 42 days. The third testing session was conducted for all the groups to investigate the follow-up effects after 42 days of non-intervention period. The data of the retained respondents from Shavasana (n=26), Meditation (n=29) and Control (n=25) groups were analyzed using Descriptive Analysis, ANCOVA, Adjusted Mean Recovery and Scheffe¿s Post Hoc Test. Additionally, the results found a satisfactory support in Qualitative Analyses.
