“AYURVEDA” is made up of two words- Ayuh and Veda. Ayuh means life and Veda means knowledge or science. Thus “AYURVEDA’ in totality means ‘Science of life’. It incorporates all aspects of life whether physical, psychological, spiritual or social. What is beneficial and what is harmful to life, what is happy life and what is sorrowful life; all these four questions and life span allied issues are elaborately and emphatically discussed in Ayurveda.
