When a mage speaks of a person’s “Life Pattern,” she means the total information available to the Life Arcanum about that person — his health, physicality, age, hunger, disease, and any supernatural effects influencing those things.
The individual symbols that make up a Pattern are referred to as Forms.
Patterns as a monolith make up the Tapestry.
