By perfectly concentrated Meditation on power, even such power as that of the elephant may be gained.

This is a pretty image. Elephants possess not only force, but poise and fineness of control. They can lift a straw, a child, a tree with perfectly judged control and effort. So the simile is a good one. By detachment, by withdrawing into the soul's reservoir of power, we can gain all these, force and fineness and poise; the ability to handle with equal mastery things small and great, concrete and abstract alike.
