When you really have something to offer to the world, then you can become truly humble. A tree when it has no fruit to offer, remains erect. But when the tree is laden with fruit, it bends down. If you are all pride and ego, then nobody will be able to get anything worthwhile from you. When you have genuine humility, it is a sign that you have something to offer to mankind.
In this world, man has two significant possessions: intelligence and emotion. These two possessions govern our day-to-day life. But very often we see that emotion (ego) gets the upper hand in our life. We know that even if someone is extremely intelligent, when his emotion comes to the fore it will devour him. He is compelled to do what his emotion asks him to do.
In the spiritual life the easiest way to conquer ego is to offer gratitude to God for five minutes daily. If you cannot offer gratitude for five minutes, then utter it for one minute. Offer your gratitude to God. Then you will feel that inside you a sweet, fragrant and beautiful flower is growing. That is the flower of humility.
