The exercise is as follows: Keep the mind fixed on the idea of Energy, and away from ordinary sexual thoughts or imaginings.

If these thoughts come into the mind do not be discouraged, but regard them as manifestations of a force which you intend using for the purposes of strengthening the body and mind.

Lie passively or sit erect, and fix your mind on the idea of drawing the reproductive energy upward to the Solar Plexus, where it will be transmuted and stored away as a reserve force of vital energy.

Then breathe rhythmically, forming the mental image of drawing up the reproductive energy with each inhalation.

With each inhalation make a command of the Will that the energy be drawn upward from the reproductive organization to the Solar Plexus.
