While constructing the Rama-setu bridge, the monkey – warriors used to write the name of Lord Rama on the stones and would throw them in the mighty ocean; the stones used to float. Once Lord Rama Himself threw the stone in the ocean and surprisingly the stone sank. When Hanuman saw this he started smiling.
Hanuman with folded hands said, “My dear Lord this is just one of your lilas. You make huge planets float in the sky so what is the difficulty for you to make these stones float in the ocean? By this act of yours, you just want to highlight that those who take your shelter will fearlessly cross this ocean of material existence but those who are discarded by you will sink in this ocean.
When we take shelter of Lord Rama then all bodily and mental suffering, disease, lamentation, distress & fear completely get vanished. Thus we can very swiftly sail through this ocean of nescience and reach to our ultimate destination.
