Material existence is full of undesirables. Things we do not want are forced upon us by some superior energy, and we do not see that these undesirables are under the grip of the three modes of material nature. When a man’s left eye, arm and thigh all quiver constantly, one must know that something is going to happen which is undesirable. These undesirables are compared to fire in a forest. No one goes into the forest to set fires, but fires automatically take place in the forest, creating inconceivable calamities for the living beings of the forest. Such a fire cannot be extinguished by any human efforts. The fire can be extinguished only by the mercy of the Lord, who sends clouds to pour water on the forest. Similarly, undesirable happenings in life cannot be checked by any number of plans. Such miseries can be removed only by the mercy of the Lord, who sends His bona fide representatives to enlighten human beings and thus save them from all calamities.
