The walls and pillars of the mandapa are covered with intricate carvings..

The Badrinath area is referred to as Badari or Badarikaashram in Hindu scriptures. It is a place sacred to Vishnu, particularly in Vishnu's dual form of Nara-Narayana. Thus, in the Mahabharata, Siva, addressing Arjuna, says, "Thou wast Nara in a former body, and, with Narayana for thy companion, didst perform dreadful austerity at Badari for many myriads of years." .

One legend has it that when the goddess Ganga was requested to descend to earth to help suffering humanity, the earth was unable to withstand the force of her descent. Therefore the mighty Ganga was split into twelve holy channels, with Alaknanda one of them. .

The mountains around Badrinath are mentioned in the Mahabharata, when the Pandavas are said to have ended their life by ascending the slopes of a peak in western Garhwal called Swargarohini - literally, the 'Ascent to Heaven'. Local legend has it that the Pandavas passed through Badrinath and the town of Mana, 4 km north of Badrinath, on their way to Svarga (heaven). There is also a cave in Mana where Vyasa, according to legend, wrote the Mahabharata.
