Manas(Psyche) in Ayurveda: Role in Cognition, Behavior, and Mental Health

Abstract

Manas (mind/psyche) occupies a central position in Ayurvedic philosophy and medicine. It is regarded as one of the three fundamental constituents of life (Tridanda), along with Sharira (body) and Atma (soul), and is responsible for cognition, perception, emotional regulation, and behavioral responses. The maintenance of mental equilibrium is considered essential for health, whereas disturbances in mental functioning contribute to the manifestation of disease. To critically review the Ayurvedic concept of Manas, its physiological and psychological functions, psychological constitutions, role in mental health, etiological factors of mental disorders, and principles of mental health management. A narrative review was conducted using classical Ayurvedic texts, including the Charaka Samhita, Sushruta Samhita, and allied philosophical literature, as well as contemporary scientific publications retrieved from academic databases. Relevant concepts pertaining to Manas, Manasika Prakriti, mental disorders, and therapeutic approaches were critically analyzed and synthesized.  Ayurveda describes Manas as an internal faculty mediating between Atma and Indriyas, facilitating cognition, perception, and behavioral regulation. Its principal functions include thinking, deliberation, reasoning, determination, and self-control. Psychological constitutions are categorized as Sattvika, Rajasika, and Tamasika according to the predominance of the Trigunas. Mental disorders primarily arise from disturbances of Rajas and Tamas, often precipitated by Prajnaparadha (intellectual error), inappropriate sensory engagement, and maladaptive behavioral patterns. Therapeutic approaches such as Sattvavajaya Chikitsa, Achara Rasayana, Medhya Rasayana, and appropriate lifestyle regulation aim to restore psychological balance, strengthen mental resilience, and promote overall well-being.
