Narad Kund is a recess in the bed of the Alakananda River which forms a pool and is close to the Tapta Kund. It is sheltered by a projecting rock which breaks the force of the river and allows people to bathe in it. Adi Shankaracharya knew this by his great powers and retrieved the idol from this pool. He is the one who has laid down the rules by which the Lord is to be worshipped. He decreed that the Rawal or chief priest of the temple should come from the state of Kerala, far down south. He also decreed that the chief priest of the temple of Rameswaram in the south, should be from the state of Garhwal. Thus he ensured that there was a good interchange between the north and south of this holy land. This tradition is followed to this day and the Rawal of Badrinath is always a Namboodiri Brahmin from Kerala, the land of Adi Shankara’s birth.
A short distance below the temple is the hot water pool known as Tapta Kund, fed by a sulfur spring which is said to be the abode of Agni, the god of fire. This water has a temperature of 130 degrees. To the left of this pool is the Surya Kund fed by a branch of the same thermal spring. These waters are said to be very nourishing to the body. The Alakananda flows swiftly just below these kunds and the boiling water falls into the icy waters of the river giving rise to clouds of steam.
