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.                                                           
                           
                           
Anoint the Lord Shiva with Love, He would give Himself
                           !! 
                           
Bilvam and flowers can be given for Shiva pooja. Please
                           go to Shiva temple for every Pradhosham and live in His grace blissfully. 
                           Pradhosha Mahima:
                           Pradhosha pooja is one of the most important among the
                           poojas performed to the Graceful Lord Shiva. In Shukla Paksha (15 moon days from New moon to Full moon) and Krishna Paksha
                           (15 moon days from Full moon to New moon) the evening of the trayodasi (thirteenth moon day) between 4.30 p.m. to 6.00 p.m.
                           is called Pradhosha. It comes once in fifteen moon days. Pradhosha time is especially meant for praying Lord Shiva. Praying
                           in that time will free us from out sins and gives moksha finally (hence the name Pradhosha). During pradoSha time a special
                           type of circumambulating called soma sUtra pradaxiNam(1) is done.
