The element Fire concerns ego, ideas, energy, and change. It is impulse. It is the will to affect the world, which burns in the proverbial soul, as well as the impermenance of the world itself. The realm of Fire is the realm of revolution and upheaval— the realm where the rawest of power could prove to be one's greatest asset.
The attainment of Fire is the mastery of impulse in the self or in the world. In the sense that it is intrapersonal, the attainment of Fire can be thought of as self-mastery, self-control, or the effective management of one's drives. In the sense that it is in the world, the attainment of fire can be thought of as managing the fires of passion among the masses, toward the end of societal achievement or adjustment— the domain of influential visionaries.
Fire-affiliated impulse is one of the most difficult forces to control, although as a powerful ally it can lend great assistance in times of need. When helpful impulses are allowed to affect the world amazing things can happen. Fire Attained can also represent the victory of such forces, facilitating successes even in the face of adversarial conditions.
The emergence of Fire can be thought of as a spark— perhaps the inspiration which accompanies a promising new idea or breakthrough. As with all Emergent elements, this card most likely represents a proverbial gift from the universe, something new related to the element Fire. Whatever it is, it likely inspires courage and confidence, or provides helpful momentum.
Emergent elements correspond with Aces in Waite-Smith and other universal tarot decks. Fire Emergent in the Two Worlds Tarot corresponds to the universal Ace of Wands.
