When pride comes we are already fallen, what comes after that is a detail.
Pride in victory, or moroseness in defeat, is useless. One should fully depend on the Supreme Personality of Godhead, who is responsible for the victory and defeat of all living entities.
As soon as we think anything is ours, pride enters our heart.
When we become proud, we think that we deserve so much. When we do not get much of what we want, we naturally become envious.
Pride brings false independence and fails one to take shelter of Lord Krishna.
Pride is so deep, that even when we are sick, we are proud of it. We tell others about our sickness, to get their sympathy and attention. But Krishna’s devotees are humble. They never want any attention from others. They keep everyone’s attention on Krishna.
