If we will think of ourselves as coming out of the earth, rather than having been thrown in here from somewhere else, we see that we are the earth, we are the consciousness of the earth. These are the eyes of the earth. And this is the voice of the earth.
If the heart wanders or is distracted, bring it back to the point quite gently... And even if you did nothing during the whole of your hour but bring your heart back, though it went away every time you brought it back, your hour would be very well employed.
