Everyone is looking to make their lives more complete. That is because without Krishna, there will always be something lacking in our lives. We are incomplete without Krishna, but when we add Krishna and put Him in front of everything else, everything else will become an aid and a support for acheiving our complete relationship with Krishna. The best way to put Krishna in front is to faithfully chant His names every day. There is nothing more important in life than this.
