Why is Sawan Somwar Vrat significant?
The Shravan month is significant because it is associated with the Samudra Manthan event that took place between the Asuras and the Devas in the Satyuga. When the poison named Halahala emerged from the cosmic ocean (Kshira Sagara), Lord Shiva consumed it to save creation from massive destruction. Therefore, Lord Shiva devotees worship Shiva on this day and express their gratitude to him by keeping a vrat. It is also believed to be the month when Mata Parvati was blessed with the boon of having Lord Shiva as her husband. Therefore, wedded couples jointly observe a vrat for a blissful married life, while unmarried girls seek Lord Shiva and Mata Parvati's blessings to get a husband of their choice.
Lord Shiva drank the Halahal and stored the poison in his throat. Due to the impact of the poison, his throat turned blue and he came to be called Neelkantha. ... Both these events took place in the Shravan Maas and therefore, it is considered very auspicious to offer holy Ganga water to Lord Shiva in this month.
