Shravan is the fifth month. It is a very important month for the devotees of Lord Shiva. Legend has it that this is the time the Gods and demons decided to churn the ocean, to please Goddess Mahalakshmi, the Goddess of Wealth. It was decided that the Gods and Demons would share whatever they get from the churning of the ocean , equally.
Eventually 14 divine ittems came from the ocean, out of which one was the deadly poison called Halahal. No one wanted to take this. This resulted in a panic among the demons and the Gods . Lord Shiva appeared at this time and drank the Halahal from the pot such that it would not pass his throat. Due to the effect of the poison Lord Shiva became blue thus getting the name Neelakantha meaning the blue throat.
To nullify the effect of the poisonous halahal, Lord Shiva was given Ganga Jal or the holy water. Since that day, the month of Shravana had devotees praying to Lord Shiva . Shravan Somvar or Monday is very auspicious as it is Lord Shiva”s day.
Any shlok or mantra that we say now, gets double effect so people chant the slokas of Lord Shiva throughout the month. They also abstain from eating meat and consuming alcohol during this month.
This year, Shravan month is from August 7, 2013.
