At some point you will not even need label what you’re doing as yoga.  It will just be the awareness of what is good for you personally.  Eventually, this awareness will ask you to face ideas within you that are deeper and more difficult.  You will feel your dharma or purpose for being here rising up.  If your actions are not in line with this duty, you might have a deep yearning to change your profession, or yourself, or the world. The ultimate question will become, “Is what I’m doing right now serving myself and the people that I affect around me?”  If it does not serve, you will need to sever. True happiness will come when our actions serve our higher Selves; the part of us that is moving towards God.
