The science of Yoga has its origin thousands of years ago, long before the first religion or belief systems were born. According to the Yogic lore, Shiva is seen as the first yogi or adiyogi and the first guru or adiguru. Several thousand years ago, on the banks of the lake Kantisarovar in the Himalayas, adiyogi poured his profound knowledge into the legendary saptarishis or "seven sages". These sages carried this powerful Yogic science to different parts of the world including Asia, the Middle East, northern Africa and South America. Interestingly, modern scholars have noted and marvelled at the close parallels found between ancient cultures across the globe. However, it was in India that the Yogic system found its fullest expression. Agastya, the saptarishi, who travelled across the Indian subcontinent, crafted this culture around a core Yogic way of life.
Yoga is widely considered as an "immortal cultural outcome" of the Indus Saraswati Valley Civilisation – dating back to 2700 BC – and has proven itself to cater to both material and spiritual uplift of humanity. A number of seals and fossil remains of Indus Saraswati Valley Civilisation with Yogic motifs and figures performing Yoga sadhana suggest the presence of Yoga in ancient India. The seals and idols of mother Goddess are suggestive of Tantra Yoga. The presence of Yoga is also available in folk traditions, Vedic and Upanishadic heritage, Buddhist and Jain traditions, Darshanas, epics of Mahabharata including Bhagawadgita and Ramayana, theistic traditions of Shaivas, Vaishnavas and Tantric traditions. Though Yoga was being practiced in the pre-Vedic period, the great sage Maharishi Patanjali systematised and codified the then existing Yogic practices, its meaning and its related knowledge through Patanjali's Yoga Sutras.
After Patanjali, many sages and Yoga masters contributed greatly for the preservation and development of the field through well documented practices and literature. Yoga has spread all over the world by the teachings of eminent Yoga masters from ancient times to the present date. Today, everybody has conviction about Yoga practices towards the prevention of disease, maintenance and promotion of health. Millions and millions of people across the globe have benefited by the practice of Yoga and the practice of Yoga is blossoming and growing more vibrant with each passing day.
