due to the curse by a sage named 'Durvasa' because Indra (the king of the Devas/Gods), had insulted a gift (garland) given by the sage, Durvasa, by throwing it onto his elephant which trampled upon it and powers The Devas(Gods) lost their strength
. . The devas/gods finally approached Lord Vishnu (preserver god) for help! . With the devas (gods) weakened, the asuras (a group of power-seeking deities or demons), moved forth to conquer them Accordingly, the Devas (benevolent gods) lost their immortality and kingdom
. He also suggested that since the nectar was hidden under the 'ocean of milk' it was not an easy task to lay hands on it (difficult task for god/s??!!!). The only option was to get the help of the Asuras or the Deomons Lord Vishnu suggested them to drink the 'nectar of immortality' to regain their lost glory
. Now, Lord Indra (King of Gods) and the other gods together with the Asuras or the demons set their foot to accomplish the mission. , by promising them a share in the 'nectar of immortality' So, the gods declare 'truce' with their only enemies, Asuras or the demons
. The devas/gods took the head-end of the snake while the asuras/demons were commanded to take the tail-end. This nectar could only be produced by 'churning' (stir milk in order to get butter) the 'ocean of milk' and by pouring certain herbal medicines into it. For this purpose, they (team of Gods and demons!) uproot and use 'Mount Mandara' as a churning stick and the serpent 'Vasuki' (king of all serpents) as the rope
As the churning continued, Mt. Mandara began to gradually sink into the mud at the bottom of the milk-ocean. In order to provide support for the mountain so it would not sink any further, Vishnu took the form of Kurma (Kurma avatar), the tortoise, and supported the mountain upon his broad back.
The devas continued on with their churning, and eventually fourteen precious articles appeared on the surface of the water. The last precious article to emerge from the ocean of milk was Dhanwantri, the Lord of Physicians, who arrived carrying a bowl of 'amrit' or the 'nectar of immorality'.
. Gods holding the head-end of the snake looked stupidly at each other! The asuras/demons who by now were tired of pulling the tail-end of the deadly king serpent were exited to see the awaited. They immediately rushed ahead and took charge of this bowl that contained 'the nectar of immortality'
. Thanks to the timely trick played by Lord Vishnu! . Dumb Asuras/demons were awestruck by the beauty of this lady, who cunningly took possession of the bowl with the 'nectar of immortality' from them and handed it over to the davas/gods Lord Vishnu, who was a turtle (Kurma avatar), transformed himself as a female (Mohini) and began seducing asuras/demons
Ladies and gentleman, this is the status of Hindu god! powerless & stupid! Gods teaming up with demons, loosing the battle, cheating, seducing...!! Afterall, what purpose did this avatar serve anyway?
