This passage comes from Robert Wearing's excellent book The Essential Woodworker, now published by Lost Arts Press.
Before trying to plane, settle the front of the plane on the job. This is vital. ------------- Now push forward steadily. Do not draw back the plane to take a swing at it. Do not disturb the 'settled' front A beginner or child will it helpful to to keep the right elbow well tucked in and to push using a body motion, as one would if trying to push the bench. When more skill has been developed, more of an arm movement may be employed. This method of planing with the arm tucked in will continue to useful for great accuracy and when the wood is unusually hard. It is particularly difficult to maintain the necessary downward pressure when the plane is at arms length.
Robert was taught by some of England's most notable craftsmen, just after WW2.
The clip on my You Tube channel was intended to show some of this technique.
