Hi Towhatend!
I get some questions about this "service to others (StO)" vs. "service to self (StS)" thing. I am not familiar with the "machine" you mention. But I will use this opportunity to adress the issue in general.
It is important not to think that doing what you like is somehow "egoistic" or StS. Developing talents and doing what you like is natural. Following your highest Joy is probably the best Service to Others you can provide. StO is not so much about "outer behavior" as it is about inner attitude. Eating a good meal in gratitude is StO as you need food to be of any use/service at all. Detaching from the fruit of ones actions is a great way of practicing StO. Simply do things because you feel Joy and Excitement by doing it. StO is not about what people "think of you" (Oh, everybody says I am so generous. I donate half my pay to charity etc.) It is not about that at all. Not expecting anything from anyone is great StO polarization. It grinds down the ego if it can be practised with "success" over time. Simply working on oneself and cleansing oneself (both mind and body) is not "egoistical", but highly polarzing towards StO. You cannot be a good mirror to others if you are full of dirt. First clean your own mirror, and then certain people will want to look in that clean mirror to see who they really are and clean themselves.
Most people are in the "indifferent zone" so to speak. They are not using their free will to polarize towards neither StS or StO. They have enough with simply getting by in the struggle of everyday life.
StS polarization is about power over others. It is about control and not allowing free will in others. It's simply cultivating one's ego and sense of being an isolated separate "I" in a very hostile world. Everyone has this ego inside them in various degrees. Free will can be used to "wear it down" or to cultivate it. The ego projects blame on to others (the world etc.) always. Taking self-responsality is a great way of wearing it down. The battle between Light and darkness is in everything, but it can only be "won" inside each individual.
To further understand the two "main paths" of StO and StS I suggest looking at RA's material here (where you can Browse by Category):
