How does the candidate affirm their intention of sincerity during the ritual?

The affirmation of intention of sincerity during the ritual is symbolized by kissing the book open before the candidate. This action represents a deep respect for the principles contained within the book, which often includes foundational texts related to the values and teachings of the organization. The act of kissing indicates a heartfelt commitment and sincerity in the candidate's intentions, signifying their dedication to uphold the responsibilities and values associated with their progression within the order.

The other options, while potentially earnest gestures, do not carry the same specific connotation of pledging one's sincerity through a physical and symbolic act like kissing the book does. Bowing to the altar signifies reverence but may not directly indicate the candidate’s intent. Reciting a pledge communicates intent verbally, but it lacks the profound symbolic gesture that the action of kissing the book embodies. Raising hands in welcome can express openness or readiness but does not encapsulate the seriousness of the commitment being made at that moment.
