Now Ravana said to himself, "These are all petty weapons. I should really get down to proper business." And he invoked the one called "Maya"--a weapon which created illusions and confused the enemy. With proper incantations and worship, he sent off this weapon and it created an illusion of reviving all the armies and its leaders--Kumbakarna and Indrajit and the others--and bringing them back to the battlefield. Presently Rama found all those who, he thought, were no more, coming on with battle cries and surrounding him. Every man in the enemy's army was again up in arms.They seemed to fall on Rama with victorious cries. This was very confusing and Rama asked Matali, whom he had by now revived, "What is happening now? How are all these coming back? They were dead." Matali explained, "In your original identity you are the creator of illusions in this universe. Please know that Ravana has created phantoms to confuse you. If you make up your mind, you can dispel them immediately." Matali's explanation was a great help. Rama at once invoked a weapon called"Gnana"--which means "wisdom" or "perception." This was a very rare weapon, and he sent it forth. And all the terrifying armies who seemed to have come on in such a great mass suddenly evaporated into thin air.
