This story is connected with Monday fast. Monday fast is practiced to propitiate Lord Shiva and Parvati. The panchakshara Mantra "Om Namah Shivaya" should be repeated on this day. The Monday fast is up to the third phase.
There are three types of Monday fast.
1. Simple every Monday fast.
2. Som pradosh fast
3. 16 weeks
Monday fast.
The rituals are same for all the three fasting. After doing the Shiva puja the story must be read or heard. The stories of Pradosh fast and 16 Mondays are separate and are given here.
Story:
Once Lord Shiva visited the famous city of Amravati. Parvati also accompanied him. On their way, they saw a beautiful Shiva temple and decided to spend some time there. One day, Parvati found Lord Shiva in a playful mood. She said to him, Oh my Lord, let us have a dice game. Lord Shiva obliged her and the game started. Meanwhile, the priest of the temple had come there. Parvati turned towards him and said Please foretell who will win this game? The Brahman gave no serious thought to her question and abruptly said, Lord Shiva will win the game. Incidentally Parvati won the game. She was angry because the Brahman had told a lie. Lord Shiva tried to pacify her, but she cursed the Brahman that he be a leper. In due course, the Brahman became a leper and spent a miserable life. After some time a few fairies descended on the earth and pitied the fate of the priest. On asking him, the priest narrated the whole episode. One of the fairies said, You observe Monday fasts for sixteen weeks without break. On the seventeenth Monday, prepare some holy food or Prasaad with flour mixed with ghee and gur. Distribute this prasaad among the members of your family and take some yourself. You will be free from this leprosy. The fairies disappeared and the priest followed the instructions. Soon, he regained his normal health. Once Lord Shiva and Parvati again visited that temple. Parvati was surprised to see the priest. He was his normal self. She enquired about this feat and the priest narrated the whole story. Parvati was happy, she also decided to observe Monday fasts for sixteen weeks. Incidentally, on the seventeenth Monday, when she broke her fast, her beloved son Kartikeya, who was displeased with her, appeared and said, 0 dear mother what is that power with which you have called me? What is the mystery? Parvati said, 0 my dear son, all this miracle is due to observing Monday fasts for sixteen weeks without interruption. Kartikeyas Brahman friend had been in a foreign land for quite some time. Kartikeya said, I shall observe Monday fasts for sixteen weeks for happy reunion with my friend. He observed the 16 weeks fasts as per rules and to his great surprise his friend returned hale and hearty. The friend enquired about the miracle and Kartikeya told him the modalities to be observed for Monday fast. The Brahman friend was very curious about his marriage. He decided to observe the Monday fasts for sixteen weeks. On the seventeenth Monday, the Brahman friend went to a city. The ruler of the city decided to marry his daughter to a person on whose neck his well-decorated elephant would put the garland. The Brahman joined the show. Incidentally, the elephant garlanded him. The ruler of the city gave him his daughter and also a lot of money. The couple departed the next day and were back in their home. On the honeymoon night, the bride said, 0 my dear, how is it that the elephant ignored all the princes and garlanded you? How did you succeed on the auspicious moments? The bridegroom said, I observed fasts on sixteen Mondays. Monday is Lord Shivas day. It is due to his blessings that I got a beautiful wife like you. My friend Kartikeya revealed this secret to me. The bride too decided to observe fasts on sixteen Mondays for a beautiful son full of knowledge. Her devotion bore fruit and she gave birth to a beautiful son. As the son grew up, he said to his mother, 0 my dear mother, what is the mystery behind my birth? Please reveal it to me. The mother told him how she observed Monday fasts. The son also decided to observe the fasts to gain a kingdom for his parents.
Incidentally, an old kings messengers from a nearby State
came there in search of a beautiful and learned bridegroom
for the princess. They proposed the princess hand for him
and he readily agreed. The king expired after sometime and
the boy became the king. The newly-made king continued his
fasts for the next sixteen Mondays. On the seventeenth
Monday, he arranged a large prayer party at a temple. All
the arrangements were made well in advance. The king
requested the queen to accompany him to the temple for
breaking the fast after taking prasaad from the priest. The
queen refused to go with him. The king had to go alone. The
king heard an oracle who echoed, 0 king, turn out the queen
from the palace or destruction will fall upon you. The king
returned to his palace. He summoned a conference of his
ministers and told about the oracle. All of them were taken
aback, as it was due to that princess that he became the
king of the state. They agreed to his proposal only with a
heavy heart. The queen was ultimately turned out. The queen
left the palace bare footed and in worn-out clothes. She was
thirsty and fatigued. She met an old lady who had a load of
spinned spindles on her head. She was going to the city. She
felt pity on her and asked to help her in selling the yarn
because she did not know the art of selling. The queen took
that load on her head. Incidentally, strong wind blew away
the spindles which disappeared in the dusty wind. The queen
felt sorry and the old lady asked her to go away. The queen
went to an oilmans house and sought shelter. The oilman
obliged her, but as she stepped in, all of his oil pots
developed cracks and the oil began to flow on the ground.
The oilman immediately turned her out. The queen was now
disheartened. She went to the bank of a river to quench her
thirst. As she touched the water, the water dried up. She
then went to a deep jungle and saw a tank of water. As she
went down the stairs and touched the crystal dear water, it
became muddy. She cursed her fate and put a few drops of the
muddy water in her mouth. She was now tired and wanted to
take rest under a shady tree. As she went near the tree its
leaves began to fall and soon it became leafless. The
cowherds saw this incident and told the whole story to the
priest of a nearby temple. The priest called for the woman.
He was surprised to see that the woman had royal features.
He consoled her and provided her with all the facilities.
But after some days, he also got fed up with her because
whatever the woman touched became impure ? may it be milk,
food or water. One day, the priest said, 0 lady, what curse
has fallen upon you? You reveal the mystery. The woman told
him how she rejected a proposal to attend Monday fast
prayer. The priest understood the whole thing. He knew it
was Shivas curse. He said, 0 dear lady, you observe fasts on
sixteen Mondays and Lord Shiva will absolve you of your
sins. The woman realised her mistake and observed the Monday
fasts for sixteen Mondays. On the seventeenth Monday, the
king said to himself, My queen left my palace long ago. Her
condition must be very miserable. He called for his
courtiers and ordered them to search out the queen. The
courtiers reached the temple where the queen was residing.
The priest refused to hand over the queen to them and said,
Let the king himself come to receive her. The courtiers went
to the king and related the whole story. The king was happy
to hear the news. He went to the temple and requested the
priest to return his queen to him. The king admitted that he
deserted the queen to avoid Lord Shivas wrath. The priest
trusted the kings words and the queen returned to the
palace. She was given a royal welcome. The king distributed
money among the needy and arranged food for the hungry. The
king and queen now regularly observed fasts on sixteen
Mondays each year and lived a very happy life. After their
death they found abode in Lord Shivas city, Shivapuri.
Since, then it is believed that a person who observes fasts
on sixteen Mondays, gets all pleasures and enters Shivapuri
after his death.
