Masters and initiates of the past left symbols as practical guides for us trying to walk the path of initiation and it would be of benefit to study these guides
as to withdraw their practical and symbolical symbolism. However, they are encoded and as such hidden from the ignoramuses and the unworthy (fornicators), but as this is the times of Acuarious and the end of this cycle draws very near, perhaps some assistance (or points of reference) can be given upon this, plausibly sacred, symbol.
For this purpose, here is the refered symbol attached and illustrated below. Thank you for your assitance.

The “Hand of the Philosopher” or the “Hand of the Mysteries” is a talisman that depicts the symbols of apotheosis, or the transformation of man into god. The Hand of the Mysteries, which features alchemy symbolism, is also referred to as the hand of a Master Mason. It is said that the symbolic hand holds the keys to divinity and a practitioner can unlock the secrets through the symbolism. Based on the teachings of Bernard de Montfaucon.
