The idea is that there are three class of men. One class of men they are simply desiring material comforts, desiring. They want nice house, nice wife, nice comfortable life, everything nice for the comfort of this body. They are called sarva-kāma. Sarva-kāma means their desire has no end.
Just like in the modern materialistic world they are trying to improve material comforts but they do not know when does it end. One after another, one after another, one after another. Therefore they are called sarva-kāma, unlimitedly desiring. There is no end of desiring. Such persons, akāma. And akāma means one who has no desire. Just like those who are devotees, Kṛṣṇa conscious, they have no desire. They don't like any material comforts, any material improvements. They want simply Kṛṣṇa. Akāmaḥ sarva-kāmo vā and mokṣa-kāma (SB 2.3.10). Mokṣa-kāma means one who is disgusted with these material desires and aspires after something void, impersonal, or freedom from all these desires, mokṣa-kāma.
So Bhāgavata says that either you are a person desiring unlimitedly or you have become free from all desires, or you are desiring liberation from this material conditional life, you please try to become Kṛṣṇa conscious. Your desires, whatever desires you may have, that will be fulfilled.
