I nodded and said, "I know. For spirits to cultivate, they must also pass through the four stages: refining essence into energy, refining energy into spirit, refining spirit into emptiness, and refining emptiness into Dao."
"The stages they experience are Spirit-Awakening, which corresponds to Qi Condensation; Soul-Opening, which corresponds to Foundation Establishment; and the Soul Dan Stage, which corresponds to the Golden Core Stage."
"After the Golden Core Stage, mortals cultivate the Nascent Soul, but because spirits lack physical bodies, they have four additional stages: Heart Refining, Spirit Devouring, Body Condensation Stage, and Animus Condensation. Only then can they refine a soul infant and catch up to the stages of mortals again."
