The tradition of Gnosis gathers the whole path into three factors. The books usually name them birth, death and sacrifice. This book met them in another order: the selves first, then the energy.
The first is death: the death of the selves. That was Part II.
The second is birth: the creative energy kept and raised, and what it builds within you. That was Part III.
The third is sacrifice for others. This part is about it.
Many people take up the first two and leave the third for later. It feels optional, something for saints. The books say the opposite. Without the third factor, the other two go wrong. Dying to the selves becomes a private project. The energy feeds a new pride. Even the night can become a hobby.
Sacrifice here does not mean making yourself miserable. It means giving something of yourself, your time, your attention, your understanding, to someone else’s good, without wanting anything back. It also means that the reason for waking up is not only your own peace. It is so that you can help.
This is simpler than it sounds. It begins with an hour given to someone who cannot repay it.
