Lifestyle diseases such as diabetes, obesity and cardiovascular disorders are rapidly growing due to sedentary living, stress and poor eating habits. Type 2 Diabetes Mellitus, in particular, has appeared as one of the most challenging public health issues. Rajyoga meditation, as taught by the Brahma Kumaris, offers a holistic preventive approach that harmonizes the body, mind and soul. This study explores the preventive role of Rajyoga meditation among adults with Type 2 diabetes. The data reveal significant improvements in glycemic control, stress levels and overall well-being. Rajyoga meditation thus emerges as a natural, non-pharmacological tool to prevent and manage lifestyle-related disorders.
