His Holiness Maharishi Mahesh Yogi is widely regarded as the world's foremost scientist in the field of consciousness.

Ayurveda is the health care system of the ancient Vedic Tradition of India and is the world’s oldest and most complete system of natural medicine. Maharishi Ayurveda® is the revival of the complete and authentic practice of Ayurveda, by Maharishi Mahesh Yogi, founder of the TM technique.
Vedic knowledge mirrors the most advanced modern scientific understanding of nature. Both see all the laws and physical reality of nature springing from their source in an abstract, non physical field of pure potentiality. Modern quantum physics has described this abstract, non-physical source of natural law as the Unified Field. The Vedic Rishis experienced this field directly and called it Veda. The Rishis experienced the Unified Field as the source of the functioning of their own mind and all of nature. They experienced it as a field of pure consciousness and unbounded intelligence.
The word 'Ayurveda' comes from the word 'ayur' meaning 'life' and the word 'veda' meaning 'to know'. Ayurveda means 'the science of life', and is a medical system practiced in India,Nepal,Tibet and Sri Lanka.
Ayurveda's mythological origins, though, are attributed to the Indo-European Nasatya or Aswins, twin physicians of the gods of the ancient Indo-European pantheon. Four thousand year old references to the Nasatya are found in the now extinct, Hurrian and Hittite languages in Turkey, and in the Sanskrit language in India. Ayurveda is considered the upaveda or accessory Veda to the Atharva Veda. The four Vedas are the world's oldest literary documents in an Indo-European language.A classic ayurvedic text, that parallels the time frame of the Atharva Veda, is the Charaka Samhita. Written in the Indus Valley area around 1000 B.C.E. (Before the Common Era) in Sanskrit, it is a treatise on general medicine. This strongly suggests the probability that ayurveda, though of pan Indo-European origins earlier, had begun to evolve into a distinct entity within the subcontinent by the first millennium B.C.E.
Ayurveda's lasting influence in the non Indo-European sphere began after the rise and spread of Buddhism in the 6th century B.C.E. Buddhist monks introduced Ayurveda to China, Tibet, Korea, Mongolia and Sri Lanka, leaving a lasting legacy in their medical systems. More recently, the German translation of an ayurvedic text that dates back to less than 1000 B.C.E., the Susruta Samhita, contributed to modern medicine the discipline of plastic surgery. Susruta mentions eight branches in ayurveda - General medicine, Surgery, ENT and Eye diseases, Toxicology, Psychiatry, Pediatrics, Gynecology, Sexology and Virility.
