pathi cyutam tisthati dista-raksitam
grhe sthitam tad-vihatam vinasyati
jivaty anatho ’pi tad-iksito vane
grhe ’bhigupto ’sya hato na jivati
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Sometimes one loses his money on a public street, where everyone can see it, and yet his money is protected by destiny and not seen by others. Thus the man who lost it gets it back. On the other hand, if the Lord does not give protection, even money maintained very securely at home is lost. If the Supreme Lord gives one protection, even though one has no protector and is in the jungle, one remains alive, whereas a person well protected at home by relatives and others sometimes dies, no one being able to protect him.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
These are examples of the supremacy of the Lord. Our plans to protect or annihilate do not act, but whatever He thinks of doing actually happens. The examples given in this regard are practical. Everyone has had such practical experiences, and there are also many other clear examples. For instance, Prahlada Maharaja said that a child is certainly dependent on his father and mother, but in spite of their presence, the child is harassed in many ways. Sometimes, in spite of a supply of good medicine and an experienced physician, a patient does not survive. Therefore, since everything is dependent on the free will of the Supreme Personality of Godhead, our only duty is to surrender unto Him and seek His protection.
