If we want something then also we have to abide by the desire of the Supreme Personality of Godhead. Then he will fulfill your desires. That is the way to do things.
Performing kirtana and hearing the vibration of the sound Hare Krishna is actually seeing the Supreme Personality of Godhead directly.
