You do not have an "extra north node".
There are only Two Nodes.
The North, and the South.
"T" is used to denote the exact mathematical position of the Lunar Nodes.
All that matters is the direction of the symbols.
Ascending Node - North Node ☊
Descending Node - South Node ☋
The intersecting paths of the Lunar Orbital Plane and the Ecliptic Plane determine the locations of the Lunar Nodes.
The Dragon's Head - North Node ☊
The Dragon's Tail - South Node ☋
Meaning, the two are not 'as one' but, 'part of one whole'. One body.
You are both the North, and the South. The Head and the Tail.
The Ascension of the Kundalini Serpent along the Sushumna from Base to Crown.
Self-Actualisation gives way to Self-Mastery.
Walking the Earth to reach the Heavens.
Future - North Node ☊
Past and Present - South Node ☋
South is the Past, North is the Future. We must not chase our tails.
For we live in the present, not the past. And walk to the future.
South is our Comfort Zone.
The known and familiar.
North is outside our Comfort Zone.
The unknown and unfamiliar.
Comfort, which is contentment, is a silent killer.
It lulls us into a false sense of security. For no comfort is forever.
There are times when comfort can feel a distant memory.
But its transient nature is what makes comfort so pleasing.
That it is only for a while, and not forever.
For if it were, we would not know comfort.
