M. (humbly): “Yes, sir. How, sir, may we fix our minds on God?”
“Repeat God’s name and sing His glories, and keep holy company; and now and then visit God’s devotees and holy men. The mind cannot dwell on God if it is immersed day and night in worldliness, in worldly duties and responsibilities; it is most necessary to go into solitude now and then and think of God. To fix the mind on God is very difficult, in the beginning, unless one practises meditation in solitude. When a tree is young it should be fenced all around; otherwise it may be destroyed by cattle.”
