"Letting go" is not a euphemism for stamping out craving by other means. As with anguish, letting go begins with understanding: a calm and clear acceptance of what is happening. While craving (the second truth) may be the origin or cause of anguish (the first truth), this does not mean they are two separate things — any more than the sprout is separate from the daffodil that emerges from it. Just as craving crystallizes into anguish, so does understanding flower into letting go.
