Bhakti and Advaita Upadeshamrita II

2. Perform all your duties with your mind always fixed on God.
As for your parents, spouse and children, serve them as your own, but always remember they do not belong to you, that they are the children of God. You are also a child of God and your own people are those who love God.

3. Cry to God with a yearning heart and then you will see Him.
People will shed a jug full of tears for the sake of their wife or children; they will be carried away by a stream of their own tears for the sake of money; but who sheds a tear for God? Cry for Him, not for show, but with a longing and yearning heart. The rosy light of the dawn comes before the rising sun; likewise a longing and yearning heart is the sign of God-vision that comes after. Extreme longing is the surest way to God-vision. Through extreme longing the mind remains fixed on the Supreme Being.
