I don't want to say to much and specially not contradict your instructor.
As well, I don't know what the end aim is of your practices.
Teachers, masters will not give you all their knowledge from day one, but rather drop by drop as you progress.
Mantak Chia might be an exception.
As you said you are a beginner, in the beginning you learn to feel energy flow, for me it was moving energy in the microcosmic orbit.
I can tell you, you can pull in energies from almost anywhere, and what you do with it is up to your abilities. Having said this, in the beginning it is important to either move it out or store it safely in the dan tien.
