He related a story of a HOPI Indian Elder in one of his books regarding the tribe not having adequate rainfall for several months.
The Hopi indian elder drove with Gregg out to an area outside of town for what was going to be a "prayer" of some type for rain. When they arrived, the elder told Gregg to stay in the truck as the elder exited.
Ten minutes later the Hopi Indian got back in the truck and said: "OK, let's go eat". Gregg asked what he did and why his "prayer" was but 10 minutes.
The elder said to Gregg that he went to an area of a sandy nature and took his shoes off. He closed his eyes and could literally feel water running over his feet and wet sand in his minds eye. He felt the moisture and the wet rain on his feet and body.
He then gave thanks to the divine creator or divine intelligence that the rain had come to his "pueblo".
2 hours later a torrential rainstorm swamped the crops and area for a few days!
Gregg says to give thanks for what is needed. Thanks implies it is "done". In other words it is not a want or desire but a completed act.
Feeling the water and rain on his feet was another way to connect to this "matrix" or "field". Feeling is the key.
