The work that the Freemasons used to do is now being done by groups such as the one I posted about--Rosae Crucis, and others. But these groups work under the direction--whether they all realize it or not--of much higher Beings. And they work for Light. Their intent is for the good of humanity, not to enslave them, for they are already enslaved.
The esoteric meaning of The Hanged Man is Submission. Submission to the Divine Will, as opposed to the will of Mind.
The Tarot existed long before the Freemasons, although groups like the Masons did help to encode the teachings into the cards during the times of persecution by the Roman Church. There was a time when the teachings were open to all, in book form, just like they are once again open to all today. Mozart was a Freemason, and of course that was the subject matter of The Magic Flute.
To worry about the Freemasons is silly--a red herring to distract you from the real work of transcending the mind.
