 Brahma then decided to perform a yajna (fire-sacrifice) at the main Pushkar Lake.In order to perform his yajna peacefully without being attacked by the demons, he created the hills around the Pushkar – Ratnagiri in the south, Nilgiri in the north, Sanchoora in the west and Suryagiri in the east and positioned gods there to protect the yajna performance.However, while performing the yajna, his wife Savitri (Saraswati)could not be present at the designated time to perform the essential part of the yajna as she was waiting for her companion goddesses Lakshmi, Parvati and Indrani.
