Avoid Prejudice
Prejudice is the greatest evil, rather the deadliest poison to spiritual life. It keeps one confined to himself, losing all access to a broader vision. It creates narrow-mindedness, and all prospects of development and progress are lost to those who pin their soul to it. Prejudice breeds hatred towards others and it is nothing but a feeling of false self-superiority in a disguised form. If you nurture this evil, you thereby add one more link to the existing chain of egoism. Consequently you remain farther away from reality. The realization of the Limitless thus becomes an impossibility.
