When Ravana leaves, Sita, forlorn and feeling abandoned, decides on suicide. She is saved by Hanuman.
She was so hurt she couldn’t suppress it any longer. She lamented, “O King [Rama], I tried to protect myself and wait for you. I didn’t have a chance to say goodbye. From now on, I’ll be gone.” She took her garment and tied her neck firmly. Then she bound it around the branch of the big sok tree. She closed her eyes and made her decision. Then the woman jumped down.
Then when the son of the wind [Hanuman, who is hiding in a tree] saw the woman, he was shocked. When he reached her, he untied the royal garment and lowered her to the earth. He saw that she wasn’t dead. He ran to her and paid obeisance at her feet.
