In the fighting between the elephant and the crocodile, the difference was that although the elephant was extremely powerful, he was in a foreign place, in the water. During one thousand years of fighting, he could not get any food, and under the circumstances his bodily strength diminished, and because his bodily strength diminished, his mind also became weak and his senses less powerful. The crocodile, however, being an animal of the water, had no difficulties. He was getting food and was therefore getting mental strength and sensual encouragement. Thus while the elephant became reduced in strength, the crocodile became more and more powerful. Now, from this we may take the lesson that in our fight with maya we should not be in a position in which our strength, enthusiasm and senses will be unable to fight vigorously. Our Krsna consciousness movement has actually declared war against the illusory energy, in which all the living entities are rotting in a false understanding of civilization. The soldiers in this Krsna consciousness movement must always possess physical strength, enthusiasm and sensual power. To keep themselves fit, they must therefore place themselves in a normal condition of life. What constitutes a normal condition will not be the same for everyone, and therefore there are divisions of varnasramabrahmana, ksatriya, vaisya, sudra, brahmacarya, grhastha, vanaprastha and sannyasa. Especially in this age, Kali-yuga, it is advised that no one take sannyasa.
