The Personality of Godhead, after hearing the elephant's plea, felt that he was in great distress. Thus at once the Lord appeared there on the Garuda, with the chakra He cut to pieces the mouth of the crocodile to save the elephant and He delivered the elephant by lifting him by his trunk. It is a promise of the Lord that His devotee will never be vanquished.
Without being self-controlled, without being disciplined and without being fully obedient, no one can become successful in following the instructions of the spiritual master and without doing so, no one is able to go back to Godhead.
By the grace of the spiritual master the cloud of the mercy of the Personality of Godhead is brought in, and then only, when the rains of Krishna consciousness fall, can the fire of material existence be extinguished.
Srimad Bhagavatam 3.21.17,
The spirit soul can be happy only in the association of the supreme living being, the Personality of Godhead, and nowhere else.
Srimad Bhagavatam 3.2.11,
