The lemniscate is a single continuous line that loops back on itself through a central crossing point — tracing two lobes that appear separate but are part of the same unbroken path. Unlike a circle (which returns to its starting point without crossing itself), the lemniscate passes through its centre, creating a figure that visits both "sides" of the crossing — both lobes — in every complete circuit.
This structure makes the lemniscate a symbol of dynamic balance rather than static unity. The circle is unity without movement; the infinity symbol is unity in perpetual motion, continuously moving between its two aspects without ever stopping in either. The crossing point is the key — it is the place where the transition between the two lobes occurs, the moment of reversal where what was above becomes below and what was left becomes right. It is the threshold between polarities, the zone of transformation.
In the Tarot, the infinity symbol appears above the head of The Magician (Card I) and above the head of the woman in Strength (Card VIII) — both cards depicting mastery and the channelling of power. The symbol signals that the power being exercised flows from an inexhaustible source — the eternal cyclic movement of the lemniscate — and that the practitioner has aligned themselves with that endless flow rather than depending on finite personal reserves.
