Śyāmasundara: One of the tests is duration.
Prabhupāda: Duration, that duration will not allow to enjoy that kind of cheating happiness.
Śyāmasundara: He rejects duty or sense of duty or conscience to be the guide for moral conduct, good and bad conduct, and he accepts only the amount of pleasure or pain as the criterion of right conduct.
Prabhupāda: Yes.
Śyāmasundara: Whether I'm doing right or wrong will be measured by how much pain or pleasure I am getting from it.
Prabhupāda: Yes, this definition we can also accept because we are try to Kṛṣṇa conscious, to derive the permanent happiness, first quality happiness.
Śyāmasundara: So if I'm feeling happy that means I am proceeding...
Prabhupāda: You must feel, if it is happiness, you must feel happy. Just like eating is happiness. So if you actually eat, you must feel happiness. It is not that (indistinct). Eating, when you are hungry, eating is happiness. But if you are not feeling happiness then what is the use of eating? By eating if you are feeling happiness, then you are eating. Strength, you'll feel strength, "Yes, I was fatigued. Now eating I am getting strength." Satisfaction. These three things are to be there when you are eating. If there is no satisfaction, no strength, then what is the meaning of eating.
