Acyutānanda: Just like if there is a pen. If I use it to kill someone, it is a weapon. If I use it to mix something, it is an instrument. If I use it to write with, then it's a pen. So it is not a pen. It is not a weapon. It is my idea that I impose on the object that makes it what it is.
Prabhupāda: No. No. Your idea, that is foolishness. But you learn from a teacher that this is pen; this is not a weapon. You have to learn it. If you don't learn it, then you will go on making experiment whether it is pen or it is weapon or it is this or that. Go on. But it will never come to any conclusion.
