No good can ever come from deviating from the path that you were destined to follow. You will be assailed by varieties of hidden pain. Most often you deviate because of the lure of money, of more immediate prospects of prosperity. Because this does not comply with something deep within you, your interest will lag and eventually the money will not come so easily. Even if your material needs are met, you will feel an emptiness inside that you will need to fill with any kind of belief system, drugs, or diversions. You will recognize how far you have deviated by the depth of your pain and frustration. You must listen to the message of this frustration, this pain, and let it guide you. It is a matter of life and death.
