Bob: I've read about there are three guṇas, passion, ignorance, and goodness, in life. And I was wishing that you could explain this somewhat, especially what is meant by the mode of ignorance and the mode of goodness.
Prabhupāda: Goodness means you can understand things. Knowledge. You can know that there is God, that this world is created by Him, and so on, so on, so many things, actual things. The sun is this, the moon is this, perfect knowledge. Even not perfect, he has got some knowledge. That is goodness. And passion means he identifies with this material body. And he tries to gratify his senses only. That is passion. And ignorance means animal life. He does not know what is God, how to become happy, "why I am in this world." Just like you are taking one animal to the slaughterhouse, it will go. But a man will protest. So this is ignorance. The goat, it is to be killed after five minutes, but if you give him a morsel of grass he's happy, he's eating. Just like a child. You are planning to kill her or kill him, he is happy, he's laughing, because innocent. That is ignorance.
