If you find your true self then you can attain your correct job in life. Attaining your correct job means helping all beings. We call that bodhisattva action. But if you cannot find your bodhisattva job, then you are the same as everyone else. Even a dog understands its job.
All animals understand their job.
But human beings don't understand their job. If you practice this way then your tantien and your mind will get a lot of energy. This is very important. If you cannot find the correct function of this energy, then maybe you will use this energy for bad actions. Sometimes this happens with people who practice martial arts like karate.
