Mystery Death of Lord Sri Rama’s brother Laxman at the end of Ramayana
After Sita was consumed by Mother Earth, Ram knew that his duties on Earth were over and he decided to return back to Vaikunth, but that couldn’t be accomplished as Hanuman won’t allow Yam, the God of Death to meet Ram.
To distract Hanuman, Ram threw his ring in the underworld (Paatal) and asked Hanuman to procure it. One day an old Saint came to Sri Ram. The Saint said that no one should enter the room in which they were having the conversation. Sri Ram directed Lakshman to guard the door of the room and said that if anyone entered the room during the conversation he will be put to death.
While this conversation was going on always-hotheaded Sage Durvasa appeared outside the room and demanded that he wanted to have an audience with Sri Ram immediately. Lakshman tried to explain the situation but Sage Durvasa became angry and threatened to curse Lakshman if He was not allowed inside. Lakshman now was left with two choice death or curse.
Soon Lakshman realized that this particular situation was the play of time for Him to disappear from earth. He readily agreed to the play of Kala (Time). He then walked into the Sarayu River and took the form of Ananta Sesha.
Sri Ram who came to know about the death of Lakshman decided that it was time to end His Avatar. He then handed over His responsibilities to his sons and bid adieu to all. He then walked deep into the Sarayu River and disappeared. Soon in the same spot Srihari Vishnu appeared resting on Ananta Sesha and blessed his devotees.
