It is to our advantage to imbibe the quality of humility, so that we don't get puffed up with a false sense of ego. Ego is basically an obstacle. Any thought which originates from our spiritual Self, devoid of ego, is a very powerful thought. It is a healing thought. We get immense power from the force of humility.
True humility is the best quality of a spiritual person.
When a person who is on the spiritual path considers himself to be even less than a blade of grass, then he experiences real freedom. It is not important how strong we are. It is important how humble we are. Humility is a quality of strength. With humility comes that inner awakened state which makes us free from the ego of small self.
