Kundalini yoga works on all levels, you become stronger in whatever you want to do. You also become stronger in your weaknesses. So it’s very important that you watch yourself closely and don’t indulge in ego driven situations. You’ll find that you can manipulate the physical world more and more. But whatever your distractions you have in life, whatever takes you away from the spiritual path will ultimately cause you to have many problems. So be aware of this consciously.
