PM Narendra Modi on Friday unveiled a 12-foot-tall statue of Adi Guru Shankaracharya at Kedarnath, Uttarakhand. Adi Shankaracharya was a mystic and philosopher born in 8th century in Kerala. He's credited with unifying Hinduism and establishing the four mutts in India. The 35,000-kg statue was unveiled at the seer's samadhi (final resting place) that was damaged in the 2013 floods.
