Our mantra is so strong that it is acting on the brain. So why don’t you take this side, that “If we are simply chanting and it is acting on the brain, even from your side, that it is so strong that we are giving up everything for this process. So how much this chanting is strong, why don’t you see to that?” Why it is happening? Why we have given everything? Our father, mother, our home, our comforts, our ideas, stereotyped, our religion, culture-everything we have given up. So don’t you see the power of chanting? You may think it is bad, but see the power. Similarly, these diseased person, if they chant, it has got power to bring him in the normal condition. The power is there. It is already proved. You say it is brainwash, but the power is there. Reaction is there. That’s a fact. You are admitting. So now, whether this reaction is good or bad, that you cannot judge because you are bad. But impersonally, if you judge, you see how the power is, that you were drunkards, you were woman-hunter, you were meat-eaters-you have given up. You cannot give up even smoking cigarette. So just this is the power. Ceto-darpana-marjanam. Why don’t you take this side?

The power is there. The electric power is there, either you use it for heater or for cooler. But the power is there. Without this power, it cannot run on, either heater or cooler. Give them this recipe. “You have to admit. You are admitting that ‘Your Hare Krsna mantra working on the brain.’ So the power is there.”
