When you have...
When you have faith in someone, you begin to like him. When you like him more, you begin to love him. When you love him, you like to serve him. When you serve him, you become humble and like to be near him, and all that ends up in deep affinity. A true affinity has no demands and no requisites. There is only one desire: to love him and to serve him and to make him happy, because you feel happy in his happiness. Such feelings for Radha Krishn is bhakti.
Along with the meditation on the form of Radha Krishn, you should also remember Their loving leelas and Their virtues, just like: They are the true friend of every humble soul (deen bandhu) and true companions to every fallen soul (patit pavan).
You should always think that your Divine Beloved (Radha Krishn) and your beloved Master are always with you and are protecting you. Never ever think that you are alone.
Remember Me every moment and continue to perform physical actions.” In other words, continuously remember Krishn in your mind and keep on performing your duties in the world. This is called karm yog
