Story of Rameshwar Jyotirlinga

 There is a legend about Rameshwaram Jyotirlinga. That when Lord Shri Ram was going to Ayodhya after liberating Sita from Ravana's captivity, at that time he stopped and rested on the Gandhamdan mountain on the way. After resting, he came to know that the sin of destroying the sage Pulastya clan is here. To avoid this curse, they should worship Lord Shiva by establishing a Jyotirlinga at this place.   After knowing this, Lord Shri Ram requested Hanuman to go to Mount Kailash and bring Shivling. Hanuman went to Mount Kailash after receiving the orders of Lord Rama, but he could not see Lord Shiva there. On this he chanted Lord Shiva carefully. After which Lord Shiva was pleased and appeared to him. And fulfilled the purpose of Hanuman ji.   Here Hanuman ji was delayed due to penance and to please Lord Shiva. And on the other hand Lord Rama and Goddess Sita keep waiting for the auspicious time for the establishment of Shivling. Due to the fear of missing the auspicious

Ketki Flowers:

 Once a dispute arose between Brahma and Vishnu as to who was the best among the two. Brahmaji was claiming to be the superior being the creator of the universe and Lord Vishnu was calling himself superior as the maintainer of the entire creation. Then a huge luminous linga appeared there. Both the gods unanimously decided that the one who finds the end of this linga first, will be considered the best.

  So both of them went in opposite direction to find the end of Shivling.

Due to lack of ends, Vishnu returned. Brahmaji also did not succeed, but he came and told Vishnu that he had reached the end. He told the Ketki flower as a witness to this. Ketki's flower also supported Brahmaji in this lie. Lord Shiva himself appeared there after Brahmaji told his untruth and he criticized Brahmaji.

  Both the gods praised Mahadev, then Shiva said that I am the cause, creator and master of the universe. I have created both of you. Shiva punished the Ketaki flower for giving false evidence saying that this flower cannot be used in my worship. That is why Ketaki flowers are never offered in the worship of Shiva.
