How can Krsna be envious of anyone? Everyone is Krsna's son. Similarly, how can Krsna be an enemy toward anyone? Since all living entities are Krsna's sons, He is everyone's friend. Unfortunately, we are not taking advantage of His friendship, and that is our disease. Once we recognize Krsna as our eternal father and friend, we can understand that He is always protecting us, and in this way we can be happy.
