Love means that everything is right with the world. Love and only love. Love means that you are content within your own heart and in the presence of the person that you love, who fills your day and makes you stronger and wiser, and gives you the confidence to go out into the world. Love is just the most beautiful, joyous feeling.
A devotee who can call on God while living a householder's life is a hero indeed. God thinks: 'He is blessed indeed who prays to me in the midst of his worldly duties. He is trying to find me, overcoming a great obstacle -- pushing away, as it were, a huge block of stone weighing a ton. Such a man is a real hero.'
Be patient. The path of self-discipline that leads to God-realization is not an easy path: obstacles and sufferings are on the path; the latter you must bear, and the former overcome -- all by His help. His help comes only through concentration. Repetition of God's name helps concentration.
