Profound Sun Dao cultivation emphasizes inner cultivation of Yang Spirit, external pure Yin, and focusing on Yin Yang balance.
This Yin and Yang does not refer to male and female, but rather to Yin Yang Qi. However, many cultivators, in seeking shortcuts, often prefer Yin Yang dual cultivation between men and women.
If it is a mutual complement between men and women, it can be considered the righteous path of cultivation. However, if one party acts as a furnace for spirit refinement, it is a lower and minor path.
Most people prefer shortcuts. Especially those among the nobility and wealthy, who cannot endure loneliness. The art of Yin Yang harvesting that drains oneself while benefiting others, yet also offers pleasure, is practically tailor-made for them as a cultivation method.
Yuan Buyin recognized this and vigorously promoted the method of dual cultivation, immediately attracting a large number of noble followers.
