Na Zi Fa - Inner Branch Energy points
Unlike the Horary points that have the same element as the open meridian, the Inner Energy points reflect the energy characteristics of the open meridian, based on the position of the sun during the day and the transition of elements. Therefor the Inner Branch Energy points actually contain the core energy of the open meridian.
Example
Between 11:00 and 13:00 local solartime the Heart meridian is open. The Inner Branch Energy of the Heart meridian is Fire. The Fire point of the Heart meridian is HT-8.
Between 11:00 and 13:00 local solartime the Heart meridian is open. The Inner Branch Energy of the Heart meridian is Fire. The Fire point of the Heart meridian is HT-8.
