As for determination, one should follow the example of the sparrow who lost her eggs in the waves of the ocean. A sparrow laid her eggs on the shore of the ocean, but the big ocean carried away the eggs on its waves. The sparrow became very upset and asked the ocean to return her eggs. The ocean did not even consider her appeal. So the sparrow decided to dry up the ocean. She began to pick out the water in her small beak, and everyone laughed at her for her impossible determination.
The news of her activity spread, and at last Garuda, the gigantic bird carrier of Lord Vishnu, heard it. He became compassionate toward his small sister bird, and so he came to see the sparrow. Garuda was very pleased by the determination of the small sparrow, and he promised to help. Thus Garuda at once asked the ocean to return her eggs lest he himself take up the work of the sparrow. The ocean was frightened at this, and returned the eggs. Thus the sparrow became happy by the grace of Garuda.
Similarly, the practice of yoga, especially bhakti-yoga in Krishna consciousness, may appear to be a very difficult job. But if anyone follows the principles with great determination, the Lord will surely help, for God helps those who help themselves.
