About three thousands five hundred observations on different Clinical features, Lung-functions and Biochemical, Haemetological, Electrophysiological, Neurological and Psychometric parameters of the trainees of the one month sadhana course programmes were selected randomly (from the database of the experiments conducted since 1992) for the statistical analysis.

Observations on 22 features were collected before and after the sadhana course (anushthan) in the laboratories of the Brahms Varchas Shodh Sansthan. These were subdivided into 10 different data sets with respect to Sex and Age Group. Optimal statistical designs were constructed for the random samples drawn from each group.
