The Qabbalah (and Freemasonry ?) can never be written nor can it ever be explained to the profane, for its own depths conceal it. Unrecognized and unknown, it stands behind the veil of human ignorance. The impossibility of materially objectifying this sacred science was well understood by the ancient philosophers. This is the true reason why there are so few students of the mystic sciences. Like all great things for which man seeks, the student of the Qabbalah must be prepared to pay the price demanded by Nature for the wisdom he receives.
The unwritten law cannot be learned; it must be evolved within the spiritual body of the aspiring seeker through right thought, right emotion and right action. When the student has actually reached the point of self-mastery, then and then only the vowels assume their correct position; the sacred centres are opened; and the Master’s word – the key to all creation – is found in man the student becomes a Master of the Sacred Name.

Our birth is but a sleep and a forgetting…trailing clouds of glory do we come from God, who is our home -Wordsworth
...it must be evolved within the spiritual body of the aspiring seeker...
This is literally correct - the greater reality resonates and manifests within the light body of the initiate so that the light body provides direct and conscious access to other levels of existence.
Hence Masonry emphasizes uprightness of life, actions and posture.
