Puṣṭa Kṛṣṇa: You mentioned earlier that not only we have to find out who is the speaker, but who is the proper person to hear the subject matter.
Prabhupāda: Yes. If somebody is interested to know what is the important thing, then he can understand this. And if he's animal, simply eating, sleeping, mating, what he will understand? Animal is not interested to know how the world is going on. He gets his food and sex. That's all. That is animal propensity. And as soon as he comes to the human platform, then inquisitive: "Ke āmi, kene āmāya jāre tāpa-traya," Sanātana Gosvāmī. He's not interested, "How I shall develop my economic position?" He has left already a very high-grade economic position. He's not interested. He's interested, "Ke āmi, kene āmāya jāre tāpa-traya (CC Madhya 20.102), actually what is my position? Why I am suffering in this material atmosphere?" That is human life.
