Chant the name of God and sing his glories unceasingly; and keep holy company. Now and then one should visit holy men and devotees of God. If a man lives in the world and busies himself day and night with worldly duties and responsibilities, he cannot give his mind to God. So it's important to go into solitude from time to time, and think about God. When the plant is young, it should be fenced on all sides. Unless there's a fence around it, goats and cattle may eat it up. When you meditate, go into the solitude of a forest, or a quiet corner, and enter into the chamber of your heart. And always keep your power of discrimination awake. God alone is real, that is to say, eternal; everything else is unreal, because it will pass away. As you discriminate in this manner, let your mind give up its attachment to the fleeting objects of this world. … Attend to all your duties but keep your mind fixed on God. Wife, son, father, mother — live with all of them and serve them, as if they were your very own. But know in your heart of hearts that they are not your own.
o As quoted in 'Ramakrishna and His Disciples' (1965) by Christopher Isherwood, (page. 265)
