Today is the first Monday of Savan, and an occasion to worship Lord Shiva. In Hindu religion, it is considered auspicious to observe on the first day of Savan in the honor of Lord Shiva, because it gives freedom and relief from the hardships of life. It also brings peace to the family of the individual. According to Hindu religious mythology, when Lord Shiva drank poison, during the churning of the sea to save the world, other gods and goddesses presented him water, to dull its effect, and which is why he is bathed in water on this day.
Those who observe fast on the day wake up early in the morning and wash themselves. Then, the pray to Lord Shiva and Goddess Parvati, by offering milk and water to the Shivling. They can also offer Sugarcane juice to the deities, for a prosper future and blessings.
They also hear the story of Sawan Somward, and then anoint the Shivling with the holy water of Ganges. Devotees also chant the Mahamrityunjaya mantra, Pankhakshari mantra for the god, and eat only at night. The food should be saltless ideally, and it is preferable if it doesn’t contain any non vegetarian element.
