We should keep in mind that no one in this material world is our enemy or friend. These two relationships are under the influence of time. As time passes, a person who is acting like our friend now, may later become our enemy. And sometimes an enemy becomes a friend.
Therefore our vaisnava philosophy directs us to give due respect to everyone and to focus on our spiritual practices. In this way, the Supreme Lord will allow us to chant Hare Krishna Maha-mantra happily and help us to cure all of our previous offenses.
