Love of Krsna is a very exalted state. For us, there is first the need for purification, for overcoming desires to enjoy the material world. When these gross desires are conquered, then there is a need to overcome the second level of desiring more subtly all kinds of recognition in spiritual life.
One must be ready to think only of Krsna’s pleasure and nothing else, without desiring any pleasure for oneself. That is love. Love means that the pleasure of the other person is first. So that is a very exalted state.
