You have to take this sword of Krsna consciousness. Then you become free. The knot [of material entanglement] is cut by this sword. How we can get this sword? Simply, with faith, try to hear. You'll get the sword.
We are getting the sword one after another, simply by hearing. I started this movement in New York. I had no actually any sword. Just like in some religious principles, they take the religious scripture in one hand and another hand, sword: "You accept this scripture; otherwise, I cut your head." This is also another preaching. But I had also sword, but not that kind of sword. This sword — to give chance people to hear.
