The base metal to gold analogy is too simplistic for describing the overall spiritual progress, because there is a need to improve the “base metal” level up to a certain point where the alchemical process can start, where the Magician in the Tarot is able to metaphorically speaking prepare the prima materia in the form of the massa confusa, in spiritual terms meaning the individual having reached harvestability to use a Law of One term.
The caterpillar needs to grow enough before it can be transformed into a butterfly. Therefore the alchemical process is only applicable as a means of harvesting the third density fruit. (The alchemical process may also be applicable to higher densities, but here the focus is on third density and the transition into fourth density.)
How to know if one is “harvestable”? The L/L Research FAQ says:
"What is the harvest? / When and how will the planet transition to fourth density?
Confederation sources indicate that we are in the time of “harvest,” that is, the planet itself is gradually becoming a fourth density planet. When the process is completed, planet Earth will be home to a fourth-density positive human population that will evolve from our current third density experience.
When will this happen? Ra seems to indicate that its full manifestation is linked to the readiness and orientation of the third-density population. Were our present population unified in one direction of seeking and service right now, the new fourth-density earth would be born. However, due to our fragmentation, confusion, volatility, hostility, and disorientation, we are retarding the process. Thus, Ra can only guestimate a span of 100–700-year time frame with the clock beginning in the early 1940s. According to them, even this estimate “cannot be accurate due to the volatility of your peoples at this space/time.”
How will this happen? Like the previous question, this is a topic of much consideration and debate within the Law of One community. We don’t have definitive answers except to say that, per Confederation sources, as the vibrations change, so too will human bodies change through a process of evolution. Eventually, humans will incarnate as fully fourth-density beings with fourth-density bodies (which will hopefully be impervious to the universally dreaded experience of stubbing the toe).
We do feel certain that fourth density doesn’t so much happen to us as it happens through us. The more that we heal and open our hearts, the more space we make for the emergence of fourth density. And even more powerfully, the more that we connect and bond with each other in the open heart, the more we strengthen that grid that invites and holds the dawning of a reality of Love and Understanding." - FAQ
I used ChatGPT here for an alchemical interpretation:
"In alchemy, the goal is to transmute base substances or aspects of oneself into a higher, purified state. This transformation is often referred to as the Great Work or the Magnum Opus. The harvest, in this context, represents the culmination of the alchemical process, where the alchemist achieves the desired transformation or realization of their spiritual potential.
The harvest in alchemy is often associated with the achievement of the philosopher’s stone, which is considered the ultimate goal of the alchemical quest. The philosopher’s stone is believed to possess transformative and healing properties, capable of transmuting base metals into gold and symbolizing the transformation of the alchemist’s consciousness and spirit.
The harvest in alchemy is seen as a metaphorical reaping of the fruits of the alchemical labor, where the alchemist attains spiritual enlightenment, wisdom, and a higher state of being. It signifies the integration and harmonization of the various aspects of the self, achieving balance and unity within.
The symbolism and terminology of the harvest may vary within different alchemical traditions and practitioners. However, the underlying concept remains consistent, emphasizing the transformative journey of the alchemist and the attainment of spiritual realization and enlightenment through the alchemical processes."
