Pradhosha Purana

Pradhosha Purana:
Once Dhevas and Asuras using the serpent Vasuki and the hill Mandhara were trying to get Amrutham (nector) from the Kseerabthi (milk ocean). Then the terrible poison Halahalam came up. All got frightened and pleaded to Lord Shiva for rescue. Being the peak of mercy Lord Shiva ate that poison. Then as per His order they resumed their effort to get Amrutham. They got it on Dhwadhasi (twelfth moon day). Without praying and thanking the God, by whom they got Amrutham, Devas started dancing and celebrating their victory.
On thrayodhasi (thirteenth moon day) they realised their sin of not praying the God and pleaded for forgiveness. The pleased graceful Lord Shiva forgave them and danced between the horns of the Nandhi (holy bull). That time is called Pradhosham. Whoever prays Lord Shiva in that time, Lord Shiva fulfills their wishes and give them mukthi.
