☉Sun
Its letter and path
Sun rides the double letter Kaph (כ), on the path that connects Chesed ↔ Netzach.
Its sphere and correspondences
Its sphere is Tiphereth (תִּפְאֶרֶת) — Beauty / Harmony, the heart center, in the world of Yetzirah.
Consciousness, balance, integration of opposites, the authentic self.
Further planetary correspondences (day, metal, incense) to be added from source.
Its tarot, in this current
The card on this path is The Sun. The Golden Dawn places Wheel of Fortune here instead, having assigned the letter to a different planet.
Its polarity
The letter Kaph carries the polarity Wealth / Poverty (Sefer Yetzirah §37). The polarity is a property of the letter; Sun supplies the energy that leans it one way or the other.
In the Sefer Yetzirah
The planetary assignment follows the Chaldean order set out at §§41 and 44; the polarity pair is given at §37 (Hayman critical edition).
Annotated passages to be added.

In this current, Sun rides Kaph (The Sun). The Golden Dawn moved Sun to the letter Resh, and reassigned Kaph to Jupiter ♃ — so on their tree the Kaph card became Wheel of Fortune.
