It is said in the Bhagavatha that a person who remembers the story of gajEndra mOksha as soon as one wakes up in the morning, is blessed with hari smaraNe during maraNa kAla.
There is a sankshipta gajEndra mOksha which is very easy for parayane.
Here are the 2 verses:

The king of elephants was held at his feet by a crocodile which was of superior strength in the lake. Taking a lotus, the elephant called out to the Lord as Adi puruSha, lOka nAtha, tIrthashravaH and shravaNa maMgala nAmadhEya.
Having heard his plea, the Lord who is apramEya, with the chakra came on the shoulders of garuDa and killed the crocodile with His chakra and freed the elephant by His hands.
