The Manomaya Kosha, according to the Panchakosha theory described in the Upanishads, is the mental sheath that governs thoughts, emotions, perceptions, imagination, and sensory experiences. It acts as a bridge between the physical body and higher levels of consciousness. A healthy Manomaya Kosha ensures emotional stability, positive thinking, self-control, and harmonious relationships. Disturbances in this sheath result in stress, anxiety, fear, anger, depression, and psychosomatic disorders. Yoga recommends a combination of ethical, physical, mental, and spiritual practices to purify and strengthen the Manomaya Kosha, leading to perfect health. The practice of Yama and Niyama forms the foundation for maintaining the health of Manomaya Kosha. Yama includes principles such as Ahimsa (non-violence), Satya (truthfulness), Asteya (non-stealing), Brahmacharya (self-restraint), and Aparigraha (non-possessiveness). These ethical values reduce negative emotions such as hatred, jealousy, greed, and guilt. Niyama consists of Saucha (cleanliness), Santosha (contentment), Tapas (discipline), Swadhyaya (self-study), and Ishvara Pranidhana (devotion to the Divine).
