what is the historical origin of the candidate's posture upon entering the lodge in craft masonry

The candidate's entry in a humble, halting posture is traditionally explained through moral and spiritual symbolism rather than a single recorded historical point of origin. In early nineteenth-century ritual explanations, this moving posture and state of preparation signified a state of poverty and vulnerability, intended to instill charity for the distressed and demonstrate to the lodge that the candidate was properly recommended and prepared 1.

When taking the obligation at the altar, kneeling on both knees was explained as the posture in which one is first taught to address the Creator, adopted by the Craft as the appropriate attitude for reception 1.

Taking a philosophical view, Walter Leslie Wilmshurst interpreted the physical state and formal trials of the candidate upon entry as a survival and reminiscence of the ancient schools of the Mysteries 2. In those ancient sanctuaries, neophytes underwent prolonged discipline, purification, and tests of fitness before being admitted to higher spiritual instruction 2.
