How long has yoga being practice in India?

Yoga has been practiced in India for at least 5,000 years, and is considered to be one of the oldest systems of physical, mental, and spiritual practices in the world. The earliest evidence of yoga comes from the Indus Valley civilization, where seals depicting figures in yoga-like poses have been found, dating back to 3000 BCE. Yoga is mentioned in the Vedas, ancient Indian scriptures, which were composed between 1500 and 500 BCE. The concept of yoga as a spiritual discipline is further elaborated in the Upanishads, which are philosophical texts from the 8th to 6th century BCE. The Bhagavad Gita, one of the most important texts in Hinduism, also mentions yoga as a means of achieving spiritual liberation. Over the centuries, yoga has evolved into various styles and schools of thought, and is now practiced by millions of people around the world.
