Practice, practice, practice. When you practice, new ways of thinking, new thoughts, come in your mind. Lectures sound good; you give a good lecture and everyone says you’re so great, but lectures are 991/2 percent not practical. For many years you must practice asana and pranayama. The scriptures say “Practicing a long time with respect and without interruption brings perfection.” One year, two years, ten years … your entire life long, you practice.
