The Buddhic Body or Spiritual Soul has his diocese within the heart. Thus, the heart temple is the diocese of what is most dignified and decent within our Being.
The fires of the heart control the Kundalini. The Kundalini (the fire of the Holy Spirit) rises under the control of the fires of the heart. The ascent of the Kundalini depends upon the merits of the heart. The path of the heart is the path of the Innermost. Therefore, the path of the heart opens up for us only with sanctity.
We receive the cross of the Initiation within the heart temple. We live the Golgotha within the heart temple. The infinite universe is a system of hearts. Therefore, the path of sanctity is the path of the heart.
The Diamond Soul or Buddhic Body must receive the five stigmata and be totally christified in order to fuse itself with the Innermost.
The Gnostic medic must follow the path of sanctity in order to Self-realize himself in depth.
