This is my path- I chose to do it for nothing.
For all that I possess, my heavenly father gave unto me. As all is a part of God, I am merely doing his service. For me, not you, I find it silly to charge my heavenly father back for what he has given me. All I know is that when I am ready, he will present it to me.
I was more of a jungle creation, 30 over years on when I look at my physical incarnation, I have an IT systems build at home; I didn't study any Information Technology stuff. I don't really know the terminologies used, I just know what to do when I am facing a problem. I go around servicing IT related stuff for nothing, they are usually the ones who can't afford repairs from shops; and this is not the only skill I possess.
As for my material requirements, I'd rather leave it all to the divines to take care of it; and I have a simple job that also provides 'service' indirectly.
Point is there is nothing wrong with the way things are practiced, it is better to be comfortable with your practice than to adopt another that makes you unhappy. One way or another, we are still servicing God. Which way do you choose to do your lightwork, what really matters is to yourself and not others, each grow according to the light within each self, I'm sure lightworkers are well aware of that.
