Tulsi
Tulsi, the daughter of Dharmaraja was a devotee of Lord Vishnu.
One day, while walking down the banks of the river, she saw Ganesha and immediately fell in love with him.
Tulsi asked him to take her as his wife, to which Ganesha politely refused by saying that he is not looking to marry anyone.
This made her furious who then cursed Ganesha that he will have to marry someone against his will.
Ganesha cursed her back saying that she will have to marry a demon and then will turn into a plan forever.
After realizing her mistake, Tulsi asked for forgiveness.
Ganesha decided to neutralize the effect of the curse by making her a very auspicious plant that will be present in every worship except for his.
In the future, Tulsi married a demon who was later killed by Lord Shiva.
