According
to some legends Vasistha was initiated into the secrets of the Sakta practices and got
spiritual success. But the Kalika Purana is silent about this. It is probable that
Vasistha came down to Sandhyacala after he was refused entry into the Kamakhya temple and
meditated on Siva. To quote Kalika Purana: -Ksobhakakhya
mahasailadaisanyam parvatottamah
TungasandItyacale nama vasisthe yatra saptavan
Niminamnastu rajarseh sapad brahmasutah pitra
Vasistho hyasarirobhuttacchapacca nimistatha
Tato brahmopadesena virjjane kamarupake
Sandhyacale tapastepe tasya visnurabhuttada
This explains the attachment of a Siva shrine to the hermitage of
Vasistha. Many devotees visit Vasisthasrama and take bath in the stream nearby to wash off
their sins.The present temple in Vasisthasrama, which
is incidentally the last Ahom monument in the neigh bourhood of Gauhati, was built in the
second half of the 18th century by King Rajesvar Singh of the Ahom dynasty. In
its plan and other architectural features this modest temple closely resembles the other
temples in the region.
