There is a legend associated with Manikarnika Ghat. It is said that at some point of time Lord Shiva was moving with his devotees. In order to avoid this her consort Goddess Parvati hid her earrings and asked him to find it. Since then Lord Shiva ia trying to find that ring at Manikarnika Ghat (Manikarnika means earning). Rani Laxmibai of Jhansi was born as Manikarnika in Varanasi taking the name from this ghat.
These two ghats are used exclusively for cremation. Hindu devotees believe that they will go to heaven if they die here in Varanasi. Old men and women visit Varanasi and wait for their judgement day. Cremation is an important activity here in Varanasi and hence separate ghats.
