Wisdom Teachings - Sat Yoga, Costa Rica

Student Question:  How do you define humility, and is it something that you can cultivate, or does it come from the heart?  Sometimes when I feel that I am practicing it, for example, if someone says something that I know is untrue, or feel that they are judging me or an injustice has been done, but I keep silent, after a while when I am alone I feel really sad and I cry.
