Now Rama gathers the whole chariot into a single glance. After naming so many parts, he arrives at the gist for which this entire description existed.
सखा धर्ममय अस रथ जाकें।
जीतन कहँ न कतहुँ रिपु ताकें॥
Friend, Rama says, whoever holds a chariot of dharma like this can be conquered by no enemy anywhere. No arrow ranks higher, no sword, no armor, no outward chariot. Above them all stands this chariot of dharma. Once a person has shaped truth, restraint, compassion, and an awareness turned toward God within himself, the outward trappings he carries do not define him.
महा अजय संसार रिपु जीति सकइ सो बीर।
जाकें अस रथ होइ दृढ़ सुनहु सखा मतिधीर॥
And then Rama says something that lifts the whole image as high as the sky. The world itself is the great unconquerable enemy, the foe hardest of all to defeat. Yet the warrior whose chariot stands firm can conquer even this enemy that is the world. Notice that Rama now calls Vibhishana matidhira, the one of steady mind. The very man who trembled with doubt a few moments ago is now named steady of intellect. This is the craftsmanship of the whole teaching. The outer battle with Ravana will surely come, and Rama will win it. The true enemy sits within, and every one of us fights that war each day. Whoever holds a firm chariot of dharma is the victor of this inner battle.
Here Tulsidas’s skill opens fully. Standing in the very middle of the war, he speaks of something larger than war. Any outer chariot can be seized from its owner. This inner chariot no one can take away. Once a person has shaped it, his victory rests on his own virtues alone and owes nothing to anyone’s grace. For this reason a single line has lingered in people’s hearts for centuries, whatever battlefield they have stepped onto.
