Curse of Sage Gautam

Sage Gautam was very pious. He was married to Ahilya . She was devotee to her husband.On the other hand Indra, who is the chief of gods wanted to marry her. But it was not possible because she was very pure and chaste. Indra had some other plans. He used to notice the daily routines of ashram of Sage Gautam. Once he got a chance to found ahilya alone at the ashram. Indra changed himself in the form of Sage Gautam. But ahilya could not able to identify indra and she considered him as his husband Sage Gautam. At the same moment Sage Gautam returned back and felt shock to see his duplicate. With his divine power he traced him as Indra. Indra was trembling in fear because his fault was caught. Indra decided to run away by changing his form into peacock.But sage Gautam blocked his way and prevent him from running and curtail his power of running. Since then it is believe that peacocks can never run fast despite being a bird. Sage Gautam cursed Indra that from now his post as king of gods will not remain permanent and one thousands wounds will be evident on his body. After this Indra's throne remains insecure forever. He is repeatedly defeated by Ravana,the king of Lanka. Once the son of Ravana Indrajit bound Indra in serpent noose(Naag Paash) and dragged him across Lanka in a humiliating display. The angry sage cursed his wife Ahilya too for not able to distinguished between his husband and other person. He cursed her to become the stone. Ahilya begged for forgiveness but the curse could not be taken back. Sage replied that in Treta yuga,when incarnation of lord Vishnu will take place in the form of Rama and she would get rid of curse when he touches you by foot.
