More on Freemasonry

I recently saw a question about Freemasonry on here and the following answer-

Yes, the "G" of Freemasonry represents the Greek Gnosis, the Hebrew Da'ath or sexual mysteries of the Tree of Knowledge. Freemasonry was once a Gnostic tradition, populated by some very prestigious, famous and Initiated individuals, including the Master musicians Giacomo Puccini, Mozart and Beethoven. However, such traditions have lost their roots; many practitioners of Freemasonry do not know the sexual mysteries at all, and have degenerated the teachings. It is possible to receive benefit from attending a Masonic Church, only if you are very well educated in Gnosis and have a lot of experience, but it is even better to attend a Gnostic Institution that maintains the three chamber system, since the mysteries of Freemasonry, as well as many other traditions, are maintained within the
Gnostic Church as re-established by Samael Aun Weor.

I have read about practices known as "Esoteric Masonry"; which is the secret that everybody wonders about I'm sure. I understand very well that it has been diluted, etc. However; I am considering joining the Freemasons as well as studying Gnosis and the Mysteries on my own. We don't have a Gnostic facility where I live; or, I would also attend there. Would it be beneficial to join the Freemasons; or, would it be harmful?
