As with most pieces like this, the"how to" of going beyond hope and fear is not dealt with, and humans are hardwired to those two emotions, as well as resistance to change! Getting comfortable with groundlessness and unpredictability takes much internal work, through presumably meditation and the courage to embrace, rather than push away, the uncertainty or "undesirable" condition. Much hard work, and much time; it will not happen overnight. It's complete overhaul of one's though processes.
