What are the means of obtaining power?

How can power be obtained?

Direct your energies with intelligence and fashion your thoughts to fruitful issues. You can find every truth connected with your being if you will watch, control and alter your thoughts, tracing their effects upon yourself, others, and your life and circumstances, linking cause and effect by patient practice and investigation, and utilising your every experience, even the most trivial everyday occurrence, as a means of obtaining that knowledge of yourself—

Understanding—Wisdom—Power.
