"Keeping nothing between" is simple and basic and we make it so difficult. It means to keep the line of connection between me and another clear and open, free of obstructions such as thinking, expectations, prejudices, preconceptions, predictions, objectives, preoccupations. Such obstructions get in between two people and interfere with connecting. When nothing is between, we can meet, person to person. Actually, I strive to keep nothing between, and am usually successful for a few seconds at a time before some obstruction slips in and I find myself talking to my thinking or expectations or some form of obstruction instead of connecting with the other. Then I catch myself and have a few more seconds of nothing between before I again allow something between. Being present, paying attention, being aware and mindful help me keep nothing between.
