Vāta is one of the three Doshas in Ayurveda, considered the controller of all bodily movements and neurological functions.
It is responsible for initiation, regulation, and cessation of physiological processes in the body.
It is asrayi (pervading all over the body) and is the controller of Pitta and Kapha.
When in its natural state (Prakrita), it sustains life and health. In its disturbed state (Vikrita), it becomes the cause of various disorders.
ETYMOLOGY
The term “Vāta” is derived from the root ‘Va gatyau’, meaning movement.
Vāta is Anila (air) and Akasha predominant, having qualities like Ruksha (dry), Laghu (light), Shita (cold), Khara (rough), Sukshma (subtle), Chala (mobile).
PRAKRITA KARMA OF VATA (NORMAL PHYSIOLOGICAL FUNCTIONS)
According to Charaka Samhita Sutrasthana 12/8:
“वायुरेव स चेष्टयिता स प्रेरकः सर्वदेहिनाम् ।”
(C.Su.12/8)
Translation: Vāta is the force responsible for all the bodily activities.
Normal physiological actions of Vāta include:
Chetanakarma (Consciousness) – Maintains alertness and life essence.
Indriyabuddhi Pravartaka (Sensory and motor function) – Stimulates sense and motor organs.
Utsaha (Enthusiasm and mental clarity) – Encourages motivation and mental agility.
Pravartaka of Speech and Respiration – Initiates speech, breathing, and other vital functions.
Gati (Movements) – Involuntary (heartbeats, peristalsis) and voluntary (limb movement).
Balakara (Strength) – Provides structural and functional strength.
Samhati (Integration) – Combines body tissues and maintains compactness.
Parvani Sphutana (Joint movement) – Enables articulation at joints.
Dhatu and Mala Vikshepana (Circulation and excretion) – Helps in movement of nutrients and waste.
Charaka Samhita Vimana Sthana 5/6:
“वायुरेव शरीरस्थो यः सर्वचेष्टितकारकः।
स एव बलवर्णादीन् धारयत्युपधारय॥”
(C.Vi.5/6)
Translation: It is Vāta within the body that governs all activities and sustains strength and complexion.
Modern correlation:
Nervous system activity (CNS and PNS)
Autonomic control of respiratory, cardiovascular, gastrointestinal systems
Reflexes and motor coordination
Hormonal regulation via Hypothalamic-Pituitary axis (movement of impulses)
TYPES OF VATA AND THEIR PRAKRITA KARMA
Prana Vata: Controls respiration, swallowing, belching, and mental functions.
Udana Vata: Responsible for speech, enthusiasm, memory, and upward movement.
Samana Vata: Assists in digestion, assimilation, and regulation of digestive fire.
Vyana Vata: Circulates blood and nutrients, supports movement and heart function.
Apana Vata: Governs excretion, menstruation, ejaculation, childbirth.
VIKRITA KARMA OF VATA (ABNORMAL OR PATHOLOGICAL FUNCTIONS)
When Vāta becomes vitiated due to Nidana like excessive fasting, fear, dryness, and exposure to cold, it gives rise to various pathological states.
Charaka Samhita Sutrasthana 28/7:
“रूक्षशीतलघुच्छिन्नविशुष्कबलहीनकाः।
शुष्ककण्ठाक्षिशिरसः प्रमुह्यन्ति च वायिनः॥”
(C.Su.28/7)
Translation: Those afflicted by vitiated Vāta exhibit dryness, coldness, lightness, cracking, dryness in mouth and eyes, and confusion.
Abnormal functions include:
Tandra, Moha (Delirium, unconsciousness) due to disturbed neural control
Kampa (Tremors), Spandana (Twitching), Stambha (Stiffness) – Neuromuscular abnormalities
Sosha (Emaciation), Karshya (Weight loss) – Malnutrition or wasting disorders
Bhrama (Vertigo), Apasmara (Seizures) – CNS dysfunction
Shoola (Pain) – Neuropathic or ischemic in nature
Vibandha or Atisara (Constipation or Diarrhea) – Improper colon motility
Anaha, Adhmana (Flatulence and bloating) – GI dysregulation
Modern correlation:
Degenerative neurological diseases (e.g., Parkinsonism, ALS)
Demyelinating disorders (e.g., Multiple sclerosis)
Autonomic dysfunctions (e.g., Orthostatic hypotension)
Neuropathies (Diabetic, Alcoholic)
Functional GI disorders (e.g., IBS)
Cachexia and muscle wasting in chronic illnesses
CAUSES OF VIKRITA VATA
Nidana (Etiological Factors):
Ruksha, Laghu, Shita, Vishama Ahara (Dry, light, cold, irregular diet)
Excessive sexual activity, old age
Ativyayama (excessive exertion), starvation
Mental stress, fear, and grief
Suppression of natural urges
Charaka Samhita Sutrasthana 20/11:
“अतियोगात् प्रवृत्तिनां वायोः स्थानान्तरं गतम्।
कुर्वत्यन्यथाकर्माणं विकारायोपपद्यते॥”
(C.Su.20/11)
Translation: Due to excessive activity, Vāta moves from its natural sites and causes abnormal functions leading to disease.
CLINICAL IMPORTANCE
In Ayurvedic diagnostics, understanding the Vikriti of Vāta is crucial in the manifestation of 80 types of Nanatmaja Vata Vyadhi (pure Vāta disorders).
Examples include:
Pakshaghata (Hemiplegia)
Gridhrasi (Sciatica)
Kampavata (Parkinsonism)
Avabahuka (Frozen shoulder)
These conditions are mainly Vataja Nanatmaja disorders, where treatment revolves around Snehana, Swedana, Basti, and Vatahara herbs.
MODERN TEXTBOOK REFERENCE
Guyton’s Textbook of Physiology:
Role of autonomic nervous system parallels Vata's function in regulating involuntary actions like cardiac, GI, and respiratory functions.
Harrison’s Principles of Internal Medicine:
Degenerative and movement disorders link closely with disturbed Vata functions.
Cognitive decline, fatigue, tremors, and neuromuscular loss can be compared to Vikrita Vata manifestations.
