how do you "absorb" energy??, or also take it in from stuff around you Options

i tried visualizing energy coming in to me but im not sure that works, so can anyone tell me if thats how you do it or is there different way???? am i supposed to feel it? how does it feel? what does it feel like??

thank you in advance for answering my questions

Chaos. That sounds very similar to how I learned to consciously absorb outside energy. The undesirability of psychic vampirism was mentioned and I agree. I don't see why people would want to pull energy out of other people when you are literally surrounded by better energy. The earth, the stars, the sun, plants all contain easily absorbed clean energy. The energy that you would pull out of an average person contains a fair bit of psychic garbage.
Normally I pull in energy with my breath and through my feet. There is some energy absorbed through hands, heart, crown etc, but primarily I pull in earth energy (tuqi/yin) through my feet, and heavenly/sky energy (tienqi/yang) with my breath. This balances the yin and yang as I mix it internally. I circulate it through what is known as the macro-cosmic orbit and this acts to pull it in and mix/ ballance it out.
