There was a demon named Jalandhar in the ancient times. He was a very courageous and a strong demon. He terrified everyone in the world. The reason for his strength was his wife, Vrinda, who was totally devoted towards him. No one was able to kill Jalandhar. Hence, all the devas and saints went to Lord Vishnu to ask for help. Lord Vishnu decided to disrupt Vrinda's devotion after hearing about Jalandhar.

Lord Vishnu left a replica of Jaladhar in Vrinda's house. This replica seemed dead. Vrinda saw this replica and started crying. A saint was passing by and asked her to stop crying. He said that he could make the body alive and there was no need to worry. As he said this, the replica came to life. Vrinda started loving the replica and hence, Jalandhar was killed in a battle with the devas.

When Vrinda came to know about this, she cursed Lord Vishnu. She said that he would have the same fate as her and would live without her wife for a long time. She also said that for this, he would have to take birth on the Earth. Vrinda then jumped into the fire in which her husband's dead body was buring. Lord Vishnu wanted to repent what he did. Lord Vishnu asked Goddess Parvati to plant Tulsi, Amla and Malti in the ashes of Vrinda's dead body. Lord Vishnu considers Tulsi to be an incarnation of Vrinda. With time, Lord Vishnu incarnated as Lord Ram and has to live without his wife for the most part of his life.
