What was required for Brother Ikeda to proceed with his request to be raised to Master Mason?

To be raised to the degree of Master Mason, it is essential for the candidate to be duly and truly prepared, worthy, and well qualified. This requirement emphasizes the importance of moral and ethical readiness as well as knowledge of the Craft. It reflects the principles of Freemasonry, which values a candidate's character and integrity in addition to their proficiency in the rituals.

Preparation involves not only a physical aspect, ensuring the candidate's readiness for the initiation process, but also a personal commitment to the values of Freemasonry. This requirement assures that the individual seeking elevation to this esteemed rank is aligned with the fraternity's standards and ethics.

In contrast, while the other options may seem relevant, they do not encapsulate the comprehensive personal and moral qualifications necessary for such advancement within the Masonic hierarchy.
