From learning the basics to figuring out the secrets on my own?

"The fifth stage of the mortal cultivation is officially called core foundation, otherwise known as true condensation. And it just so happens to be the stage that we are both currently on, meaning, it's also the last stage I can explain with a degree of expertise or depth."

Claire's lecture continued without even the slightest disturbance, fanfare or the audience clapping, and yet… 

And yet I could tell that just as she earlier divided mortal cultivation into three phases, now that we started to talk about the second step of it, this was going to change and do so in a hurry. 

"This stage is all about taking the spiritual energy you've gathered, condensed and then refined… and then condensing it again, beyond the limits of what you thought or felt possible before."

The noise of Claire's steps once again reached my ears, signifying she had resumed her stroll around me in this dojo-like part of the living room.
