What is signified by pressing the right breast on the sharp angle of a square during initiation?

Pressing the right breast on the sharp angle of a square during initiation is a symbolic act that represents the rule of morality and virtue. In Masonic symbolism, the square is a tool used to measure and align actions according to moral standards. By placing the hand on the sharp angle, the candidate expresses a commitment to uphold these virtues as they progress in their Masonic journey.

This action serves as a reminder to the initiate of the ethical responsibilities that come with their new role and the importance of aligning their actions with moral principles. It encapsulates the essence of integrity and moral conduct that is central to Masonic teachings, reinforcing the candidate's dedication to living a life guided by virtue.

The other options highlight significant aspects of Masonic initiation, but do not capture the specific significance of the action as effectively. For instance, while readiness to learn and the beginning of a journey are critical components of the initiation process, the pressing of the right breast specifically underscores the importance of morality and virtue in the life of a Mason.
