Drawing on the scientific and technological legacy of ancient India, Prof. Saroj Sharma discusses how integrating traditional knowledge systems with modern education can promote holistic learning, sustainable development, ethical values, and scientific innovation for future generations.Ancient India is one of the civilizations that gifted humanity an invaluable scientific and technological heritage. The origins of modern engineering can be traced to the excellent urban planning, drainage systems, and sophisticated metallurgical skills developed by the Indus Valley Civilization (3300–1300 BCE). The earliest examples of agricultural technology, metallurgy, and astronomical calculations are found in the Vedic Age. These innovations later laid the foundation for a well-organized scientific tradition. From the Rigveda to Aryabhata, Sushruta, Charaka, Varahamihira, and Bhaskaracharya, this tradition of knowledge continued to evolve.In ancient times, the famous Indian universities of Nalanda, Vikramshila, and Takshashila spread knowledge in the fields of philosophy, astronomy, mathematics, and medicine. Aryabhata’s Aryabhatiya (499 CE) gave formulas for trigonometry, the heliocentric theory, and the Earth’s circumference (39,968 km). Bhaskaracharya’s Lilavati laid the foundation of algebra, while Brahmagupta formulated the rules for negative numbers. The Sushruta Samhita is the first medical text on surgery, plastic surgery, and cataract surgery. The Charaka Samhita is an encyclopedia of internal disorders. Nagarjuna’s Rasashastra teaches methods for preparing medicines. In astronomy, the Surya Siddhanta accurately calculates eclipses and planetary movements. Varahamihira’s Panchasiddhantika synthesized five astronomical systems. The Iron Pillar of Delhi (400 CE) is an unmatched example of rust-free steel metallurgy. The path of the sun, wind direction, and balance of the five elements form the basis of Vastu Shastra.Relevance of Ancient Indian Science in Present-Day EducationIn the 21st century, while Artificial Intelligence like ChatGPT and Generative AI, private space flights, immersive technologies like AR and VR, smartphones, 5G, social media, drones, humanoid robots, gaming, machine learning, and 3D printing have impacted almost every area of human life, this century is also grappling with environmental crises, climate change, mental health issues, and a lack of ethical values.This is not only a matter of serious reflection, but also a question about the very existence of human life today. Such a situation compels us to reconsider our ancient Indian science and technology.Ayurveda and Holistic Health EducationAyurveda specifically focuses on the preservation of human life, animals, and plants. Ayurveda is the traditional system of Indian medicine that includes knowledge related to both mind and body. Ayurveda is the complete science of a healthy lifestyle. Its main principle is: “Swasthasya swasthya rakshanam, aturasya vikar prashamanam cha” Meaning: Protect the health of a healthy person and cure the disease of the sick. Its relevance remains equally important in the 21st century.Ayurvedic education emphasizes Dinacharya, which includes waking up during Brahma Muhurta, exercise, bathing, and contemplation. This education makes students disciplined and healthy. Rtucharya includes the six seasons of the year — Shishir, Vasant, Grishma, Varsha, Sharad, and Hemant — which help in balancing the doshas. For example, during summer, Pitta and Vata energies increase in the body. Hence, one should consume sweet and cold foods like fruits. Adequate water intake is necessary to maintain hydration levels.In ancient India, diet was also based on science. It teaches the proper intake of the six tastes (Shadrasa: sweet, sour, salty, pungent, bitter, astringent) to balance the doshas. The Charaka Samhita states: “Roga sarve mandagnau” — meaning weak digestion is the root cause of all diseases. Therefore, food should be consumed in moderation according to one’s digestive power.Ayurveda also describes mental health. It uses the three gunas — Sattva, Rajas, and Tamas — to describe mental nature. This promotes mental balance and personality development.Today, millions of people suffer from lifestyle diseases like diabetes, hypertension, obesity, and heart disease, which have taken epidemic proportions and are putting serious pressure on the public health system. India has the second-highest number of adults with diabetes globally. In the present scenario, education based on Ayurvedic principles has become extremely important for a healthy lifestyle.Ayurveda addresses these lifestyle diseases like obesity, hypertension, and diabetes through dosha balance using Dinacharya, Rtucharya, and Trayopastambha.Today, Ayurveda has both global and national recognition. 80-90% of the world’s population depends on traditional systems of medicine like Ayurveda, and the World Health Organization (WHO) considers these systems essential for healthcare. The establishment of the WHO Global Centre for Traditional Medicine in India is proof of Ayurveda’s contribution in contemporary epidemics.Since 2017, the AYUSH departments of AIIMS institutions like AIIMS Rishikesh have been treating lifestyle disorders by integrating contemporary medicine with Ayurveda based on Tridosha principles. Since 2017, the All India Institute of Ayurveda in New Delhi has been fully operational, promoting education and research on the AIIMS model. The National Institute of Ayurveda and other organizations are institutionalizing these efforts.Modern Stress and the Solution of Ancient YogaToday, children go through many kinds of stress, which keeps their minds anxious. The main causes include pressure from exams and social media. According to Maharishi Patanjali’s second sutra — Yogashchitta vritti nirodhah — yoga is the restraint of the fluctuations of the mind. That is, mental peace is achieved only by controlling the restlessness of the mind. According to NEP 2020, along with studies, it is also necessary to understand oneself.Ancient Indian traditions present a holistic approach to mental health, including physical, mental, and spiritual well-being. The Vedas, Upanishads, Bhagavad Gita, and Ayurveda are ancient texts that address psychological problems, encourage mental peace, and guide toward a balanced life. For example, modern sound therapy and mindfulness-based practices are related to the descriptions in the Atharvaveda of the calming effects of mantras and healing sounds.Maharishi Patanjali’s Yoga Sutras present the Ashtanga Yoga system — Yama, Niyama, Asana, Pranayama, Pratyahara, Dharana, Dhyana, and Samadhi — an integrated science of mental, physical, and spiritual well-being. It is the gateway to complete human development.Yoga education improves health by increasing physical flexibility and strength, boosting immunity, and improving the respiratory and digestive systems. Mentally, it reduces stress and anxiety. It enhances concentration, memory, emotional balance, and self-confidence. It promotes self-knowledge and self-realization, a positive outlook toward life, and the development of compassion and empathy.The support of 177 countries for International Yoga Day, celebrated on June 21, 2015, in India by the United Nations, is proof of yoga’s global acceptance. The Government of India has made yoga education compulsory in schools. Research on yoga and meditation has also developed in prestigious universities like Harvard and Stanford.Modern Sustainable Development and the Ancient Indian PerspectiveDespite immense success in science and technology, we are struggling with environmental crises and lifestyle diseases in modern times. One reason is the lack of awareness among students regarding respect for the environment and sustainable lifestyles. In ancient India, the environment was not seen merely as an object, but as living and conscious. The Atharvaveda mantra “Mata Bhumih Putroham Prithivyah” states that Earth is our mother and we are her children. Therefore, protecting the Earth is our spiritual and moral duty.To conserve the environment, forests were addressed as “Aranyak” and “Tapovan”, and trees like Peepal and Neem were called “Devavriksha” and socially protected. Ancient Indian water management techniques were based on rainwater harvesting. Rainwater harvesting has become a necessity today. Similarly, the principles of the Panchatantra and Hitopadesha taught compassion and tolerance toward animals and birds from childhood as the basis of moral values.Today we are facing the side effects of excessive production of chemicals. In ancient India, agriculture was based on mixed farming, organic manure, etc. Meanwhile, the side effects of chemical fertilizers and pesticides have become a challenge today. Climate change and water, air, and land pollution have emerged as a global crisis.In this time of global crisis, there is a need to re-integrate our Vedic, Puranic, and folk traditions into education. This step will lead humans toward environmental conservation from childhood and inspire them scientifically and ethically.The notable achievements of the Indian Space Research Organisation (ISRO) — Mangalyaan (2014), Chandrayaan-1, Chandrayaan-2, and Chandrayaan-3 (2023) — are living examples of the inspiring influence of traditional Indian mathematics and astronomy.For example, Aryabhata’s 5th-century Aryabhatiya presented the heliocentric model and calculated Earth’s circumference as 3931.6 miles, which is remarkably close to the modern figure of 3950 miles. Other examples like the elliptical motion of planets and the zero-decimal system, planetary motion in Varahamihira’s Panchasiddhantika, and planetary calculations in Bhaskaracharya’s Lilavati and Siddhanta Shiromani form the basis of contemporary space calculations.Including ancient astronomy along with modern astronomy in the education curriculum — such as the traditional theory of the motion of the 12 zodiac signs and modern Kepler’s laws — will awaken mathematical-astronomical consciousness in students. On the other hand, it will also inspire them to become part of national institutions like ISRO in the future.In line with the National Education Policy 2020, integrating India’s Vedic-classical scientific heritage with STEM education will restore it. This will also inspire the next generation to promote indigenous pride and global leadership.Ancient Vastu Shastra and Modern ArchitectureAncient Vastu Shastra is a deep study of the scientific principles of building construction. It ensures natural light, ventilation, energy flow, and environmental harmony based on the movement of the sun, wind direction, Earth’s magnetic field, and balance of the five elements. In modern architecture, it is applied in green buildings, energy-efficient construction, natural lighting, air conditioning, rainwater harvesting, and solar energy. In LEED (Leadership in Energy and Environmental Design) certified buildings, up to a 30% reduction in energy consumption has been observed with the northeast direction (Ishan Kon) as per Vastu. According to studies conducted at IIT Kharagpur and other institutions, the open courtyard system of Vastu (natural light-atmosphere) has demonstrated 40% energy savings compared to contemporary passive cooling. The use of local resources has reduced the carbon footprint.The National Education Policy 2020 supports the inclusion of Vastu Shastra in architecture curricula. Green certification, solar system analysis, and temple/haveli case studies will increase students’ awareness of sustainable design, helping to revive scientific heritage for zero-energy and climate-resilient structures and achieve global sustainability goals. In the school curriculum, students should be taught solar calculation software analysis and green certification. This will help restore ancient scientific heritage for climate adaptation and zero-energy buildings and contribute to global sustainability.The scientific and technological past of ancient India is not just a chapter of history, but a guide for the present and future. It showcases a wide spectrum of human genius — from mathematical abstraction to precise surgery and excellent metallurgy. Indian education systems now need to include this heritage in the core curriculum. The aim is not blind imitation of the past or glorification of unscientific claims, but to provide education rooted in cultural foundations with a global perspective. This will help children understand that science is a universal human endeavor in which their ancestors also made significant contributions. It will encourage them to adopt a multidisciplinary, comprehensive, and sustainable approach. An Indian student will not just learn basic facts, but will be inspired for continuous learning and questioning.(The author is a renowned educationist and currently the Vice-Chancellor of Ranchi University)
