Life is not finished by this body. It is a chance. It is a chance only. Just like you are going somewhere and you . . . on the way you find so many stations, some of them not very good and some of them very nice. Similarly, this human form of life is a station of our journey. We have begun our journey since we separated from the Supreme Personality of Godhead to become happy without God's connection. Therefore our journey has begun, we do not know when it has begun, but it is going on through different species of life. Dehāntara-prāptiḥ (BG 2.13). Dehāntara means one body after, one body after, one body after it is going.
So here in this human form of body is a chance. Lower than this human form of life you cannot understand self, ātma-tattva. It is not possible. But you can understand in this human form of life what is ātma-tattva. If you miss this chance, if you do not work to understand what is ātma-tattva, what is self, what is Superself, what is the spiritual world, how things are going—so many things you have to know—if you don't know, if you don't try to know, then you are missing the point. And missing the point, we are busy.
