There is a subtle but decisive difference between wanting a thing and having it. Wanting is a state of lack — it quietly affirms that the wish is absent. Having is a state of fulfillment, and it is the only state that creates.
Neville’s instruction is to occupy the having: to feel the relief, the gratitude, the ordinariness of the wish already granted. Done sincerely, the restless wanting falls away — and with it the very sense of lack that kept the wish at bay.
Catch one “I want…”. Rephrase it as “I have…”, and stay with the feeling that brings.
Where have you been wanting from lack rather than living from having?
