It is often explained as a higher place or the holiest place in contrast to hell. Heaven is considered as "Swarga loka", and the soul is subjected to rebirth in different living forms according to its "karma". In the Vaishnava traditions, the highest heaven is "Vaikuntha". Entry into heaven or swarga loka or hell (Naraka) is decided by the Lord of death Yama and his Karmic accountant Chitragupta who records the good and bad deeds of a person during his lifetime. Entry into heaven is dependent on ones action in the previous life and is not restricted by faith or religion.
