Ayurveda is the most ancient science of all the medical sciences. Like Yoga, it is also based on Samkhya philosophy of creation and manifestation.
The union of body, sense organs, mind and soul is called ‘Ayu‘; ‘Veda‘ means knowledge. Thus, ayurveda is the ‘science of health’, ‘science of longevity’, ‘science of life’. Ayurveda therefore is not simply a health care system but a form of lifestyle adopted to maintain perfect balance and harmony within the human existence i.e. from the most abstract transcendental values to the most concrete physiological expressions based on premise that life represents an intelligent coordination of the soul, mind, senses and physical body.
Samkhya means ‘right knowledge’; it also means ‘numbers’. Samkhya is one of the oldest systems of Indian philosophy. It occupies a unique place among the six systems of Indian philosophy. Almost all branches of Indian literature reflect the influence of Samkhya Philosophy. This system is sometimes, described as the ‘atheistic Yoga’ as distinguished from Yoga Philosophy, which is also referred as ‘Theistic Samkhya. This system is accepted as the main opponent of Vedanta Philosophy which is a non-dualistic philosophy; whereas, Samkhya maintains a clear-cut dualism between Purusha (Pure Consciousness, soul) and Prakriti (nature, manifested being, mind-body complex); further maintains the plurality of Purusha, and is silent on God. It is often also referred as pluralistic spiritualism, an atheistic realism and uncompromising dualism.
International Day of Yoga (IDY), is celebrated annually on 21 June since its inception in 2015. The idea of International Day of Yoga was formally proposed by the current Prime Minister of India, Shri Narendra Modi during his speech at the United Nations General Assembly (UNGA), on 27 September 2014. He stated;
Yoga is science of life carrying
in it the mystery of conservation of health and complete transformation of
life. Its techniques offer remedies of health and hygiene chiefly because these
are half therapy. Yogic therapy contributes to the integration of personality
through healthy body and mind with minimum of time, effort and expense. This is
attained by promotive, preventive and curative methods. Whereas Promotive
methods bring in homeostatic functioning in the body, Preventive methods
protect individuals from exposure to bad influences and Curative methods bring
cure in the disturbed psychophysiological function.
