Best Qigong exercises?

[Mulberry]

To “generate energy”? What kind of energy? Do you mean that or do you mean cultivate qi.

To generate energy from your Jing just means you are using up your Jing faster and will die sooner, you don’t want to do that.

You want to use full body breathing to draw energy into you, aka to cultivate it, then acclimatize and balance it inside your qi body using the microcosmic orbit.

Cultivating qi is very simple.

@Mulberry

Full body or pore breathing. You visualise the energy you want to cultivate, I like to send my mind out as far to the edges of the cosmos as I can imagine, and see the energy flowing in and filling your body with your breath.
Then, as you breath in, instead of just breathing in through your mouth, see you entire skin all over breathing in the energy through your pores and energy points as well.
As the in breath completes, your body is full of light, or Qi.
