When Adi Shankaracharya was 11 years old he and his fellow disciples arrived at Badrikashram. When he reached there early in the morning the fresh and divine breeze of Sushmaand Gandhmadna mountain moved him greatly and he spontaneously started reciting the Ashtapadi. After a few days he started looking for the divine idols of Badrinath along the southern part of the Alaknanda river. As he excavated along the left bank of the river he felt certain that the Naradkund also known as the Narayankund was between the Naradshila and the Varahshila. With this belief he dived into the pond. He found an idol. On bringing it out of the water and closely inspecting it he felt that it did not have any distinctive features to indicate it was a divine idol. He put it back into the water and again dived into the Narayankund and again found an idol but did not find anything distinctive about it. He dived the third time and again found an idol and just when he was about to put it back into the water a voice stopped him, which said that
‘I am Badrinath and have been consecrated by Brahma once before,'
The voice asked him to give this divine idol its rightful place.
Thus about 2500 years ago Badrinath was consecrated and worshipped by Adi Shankaracharya. The rituals and procedure of worship as laid out by Adi Shankaracharya is being practised at Badrinath till today. Srimad Bhagvad Gita has explained the significance of the temple and glory of Lord Shri Badrinarayan.
