The intricate and multidimensional framework of Ayurveda encompasses not only the physical body but also the subtle aspects of human existence, including the mind (Mana) and consciousness (Sangya). Within this paradigm, the concept of Shrotas-channels responsible for the transportation of various bodily substances-extends to subtle mental pathways, particularly the Sangyavaha Shrotas, which are said to facilitate the transmission and regulation of cognitive functions, emotions, perceptions, and awareness. These channels are closely related to the activities of Mana, which functions as an internal coordinator of the sensory organs and a pivotal component of mental and emotional health.
While classical Ayurvedic texts provide limited direct anatomical descriptions of Sangyavaha Shrotas, their existence is inferred from the functions and dysfunctions of Mana described in texts like the Charaka Samhita, Sushruta Samhita, and Ashtanga Hridaya. These scriptures link Mana to the heart (Hridaya), the ten great vessels (Dasha Dhamani), and to subtle faculties such as memory (Smriti), intellect (Buddhi), and self-awareness (Ahamkara), suggesting an elaborate network of subtle channels that mirror modern neurological and psychological processes.
This review aims to analyze the classical references and theoretical foundations of Sangyavaha Shrotas, exploring their physiological roles, their association with mental and psychosomatic diseases, and the Ayurvedic diagnostic and therapeutic strategies aimed at restoring their balance. Furthermore, the paper draws parallels between Sangyavaha Shrotas and modern concepts in neuroanatomy, such as neural networks, neurotransmitters, and the central-peripheral nervous system interface. It highlights how dysfunctions in these subtle channels may correlate with mental health disorders like anxiety, depression, insomnia, and psychosis, and how they may influence or be influenced by systemic conditions like hypertension and irritable bowel syndrome through the mind-body connection.
By integrating ancient Ayurvedic perspectives with emerging insights from neuroscience and psychoneuroimmunology, the study underscores the relevance of Sangyavaha Shrotas in both preventive and curative aspects of holistic health care. It also emphasizes the importance of Ayurvedic approaches—including Sattvavajaya Chikitsa, Medhya Rasayana, Panchakarma, and mind-body techniques like yoga and meditation—in maintaining the integrity of these channels. The exploration of Sangyavaha Shrotas thus opens new avenues for integrative mental health interventions rooted in traditional knowledge but validated through modern science.
