It's a great science, Kṛṣṇa consciousness. It is not that we are simply concerned with worshiping this Deity. No. We have got volumes of book. It is . . . it is a science how to make people happy in this life as well as the next life. Not only in this life, but in the next life. Because this life is preparation for the next life. Just like childhood, boyhood, youthhood is the preparation for the next life. Why we send our children to school? Because that is preparation for the next life. Otherwise let him play all the night, all the day. Why you should be, parents, why anxious to send him to educational institution? It is preparation for the next life.
Similarly, this life is also meant for next life. Evolution. Why evolution? From aquatics to the birds, beasts, insect, animals, then we come to the human form of life, especially in a civilized human form of life. So if you prepare yourself in this life, then next life you can improve more. You can become demigod; you can go to higher planetary system, where duration of life, standard of comfort, is very, very high, thousand times, thousand times comfortable than at the present moment. Similarly, you can transfer yourself to the abode of God.
