Having respect for others without seeking any compliments, being humble and always forgiving, all of these virtues can be expressed in one word, Humility. It is the foundation of devotion. Devotion starts, stays, and develops only on the basis of humbleness. Any touch of pride and ego spoils it, just like a pinch of salt spoils a cake. Pride or ego is an obstacle in devotion. Humbleness of a devotee develops dedication to his master and dependence on God's Grace.
