So diseased condition means contaminated by māyā. This is external. So our philosophy, Kṛṣṇa consciousness movement, is not to stop desiring but purify desiring. And how you can purify? By Kṛṣṇa consciousness. If you desire . . . just like—concrete example—if I desire a very nice apartment for my personal sense gratification, this is diseased desire. And if I desire a nice, costly temple for Kṛṣṇa, that is purified desire. So desire is there. You are sitting here in a very nice room, very cleansed, very good atmosphere. But this desire is purified desire. And if you require similar room for your sense gratification, that is impure desire.
So desire there must be. But when it is desired for Kṛṣṇa, it is purified desire, and when it is desired for non-Kṛṣṇa, then it is impurified. So those who are desiring for Kṛṣṇa, they are not behind any enjoyment. They are rather in perfect enjoyment. These Kṛṣṇa conscious students, they are desiring for Kṛṣṇa nice prasādam, so they are not bereft. Practically they are enjoying, but it is Kṛṣṇa-ized. Therefore their everything is becoming purified. This is the science.
