Rishi Atri’s wife Anusuya was very loving and devoted to him. She was a “Pativrata” (Pativrata means one who is loyal and faithful to the husband). Sage Narada visited Rishi Atri’s ashram and was very impressed with Sati Anusuya’s loyalty, dedication and devotion to her husband and praised her in front of Goddesses Saraswati, Lakshmi and Parvati the wives of Gods Brahma,Vishnu and Shiva respectively. The Goddesses were jealous of Anusuya, so they decided to test her loyalty. They came about a plan. The 3 Gods went to Rishi Atri’s Ashram as guests, when Rishi Atri was not there at home and asked Sati Anusuya to serve them (lunch) without putting on any clothes. Sati Anusuya agreed to this, she meditated upon her husband and sprinkled water on them and converted them into 3 babies. The three goddesses who were waiting for their husbands to come back arrived at the scene to find their husbands being converted to babies. They immediately regretted their plan and asked Sati Anusuya to forgive their husbands and themselves. Sati Anusuya forgave them but asked for the three Gods to be born as her 3 sons. "The gods were then born to her as her sons Soma, Dattatreya and Durvas.
In Ramayana, Ram and Sita are also said to have visited Sati Anusuya and she narrated to Sita the importance of loyalty to one's husband.
There is yet another story associated with her. Chitrakoot did not receive rain for several years. This led to a famine. Sati Anusuya prayed hard and the power of her prayers brought the river Mandakini down to the earth. Then there was greenery all around. The human beings and animals were also relieved. Such is the power of a pativrata and the mahima of a lady who is devoted. She can move 3 worlds.
