Chennai: Prime Minister Narendra Modi will unveil a 112-ft tall face of Lord Shiva or 'Adiyogi' at Isha Foundation in Coimbatore on Mahashivaratri, which is on February 24.In a statement Isha Foundation said on Saturday that the face will be largest such on the planet, recognising the first yogi's unparalleled contribution to humanity."This iconic face symbolises liberation, representing the 112 ways in which one can attain the ultimate through the science of yoga," the statement said.According to the Foundation, on Mahasivaratri (February 24) Modi will light the sacred fire to commence the 'Maha Yoga Yagna' across the world when one million people will take oath to teach a simple form of yoga to at least 100 persons in the coming year."For the first time in the history of humanity, Adiyogi introduced the idea that the simple laws of nature are not permanent restrictions. If one is willing to strive, one can go beyond all limitations and attain liberation, moving humanity from assumed stagnation to conscious evolution," Isha Foundation founder Sadhguru Jaggi Vasudev said in the statement.Describing the significance of Adiyogi, Vasudev said: "It is essential that the coming generations on this planet are seekers, not believers. As philosophies, ideology, belief systems that don't stand the test of logic and the scientific verification will naturally collapse in coming decades, you will see the longing for liberation will rise. When that longing rises, Adiyogi and the science of Yoga will become very important."
