This series of exercises is only offered to advanced students
of the Dao Yuan School after completion of Nei Jing Gong_3. It
is taught over five weekends and originates from the free
tradition of Daoism, the "Dao Jia", i.e. it was handed down
outside the monasteries. This series consists of five exercises
designed to develop the five manifestations of the mind: the
Yin Shen, the Yang Shen, the Yuan Shen, the Sheng Shen and the
Yu Shen. (Yin Shen: in the understanding of this tradition,
part of the maternal inheritance; Yang Shen: part of the
paternal inheritance; Yuan Shen: one's essential spirit; Sheng
Shen: Spirit of Wisdom; Yu Shen: Jade Spirit).
