To breathe in consciously is to know that the air is entering your body, and to breathe out consciously is to know that your body is exchanging air. Thus, you are in contact with the air and with your body, and because your mind is being attentive to all this, you are in contact with your mind, too; just as it is. It needs only one conscious breath to be back in contact with yourself and everything around you, and three conscious breaths to maintain the contact.
