We all recognise that the alchemical work takes place on many different levels - the physical work with substances, the experience and manipulation of etheric forces, the interior work on the soul, as well as the spiritual and planetary/cosmic aspects of alchemy.
The tradition of interior development in alchemy, is pursued by mirroring the transformations and processes of alchemy within our soul. As with any esoteric practice, this internalising of alchemical operations can produce disturbing patterns in the powerful psychic energies that we evoke through inner work, unless we find some means of containing these energies. In the tradition of ritual ceremonial magic the operators normally use an opening and closing ritual that acts as a structure to contain and safely dissipate the energies raised through their work. Similarly, in many traditions of meditation, an opening and closing exercise (sometimes based on breathing rhythms) helps to anchor and reconnect the meditators with their normal state of consciousness, so as not to leave them rather dissociated and dangling somewhere in between the outer and interior worlds. In inner work with alchemical processes it is found that the symbol of the alchemical vessel is an invaluable means for containing the interior energies and allowing them to unfold within us in a controlled and positive manner. So in a sense, the alchemical vessel can be a protective interior symbol, just like the circle of the ceremonial magician, or the astral temple of a working esoteric lodge, or the breathing exercises of a meditation tradition.
The energies evoked by working with alchemical processes, can be powerful and disruptive forces in the psyche, and a direct inner encounter with these transformative energies is not to be had instantaneously. Only through long and repeated interior work do we come to directly experience these energies in their primal and most fundamental form. The initial encounters are usually ephemeral and overlain with emotional currents. Only if we have the patience of alchemists tirelessly repeating interior experiments, brooding over our inner flask, will we attain even a glimpse of the goal of alchemical transmutation. It is therefore important that we understand the nature of the alchemical vessel so that we have some indication of how to use this in our inner work.
There are many different forms of vessel described and depicted in the alchemical literature and emblematic engravings. There are a seeming multiplicity of forms of retort, pelicans, water baths, alembics, cucurbites, stills, etc. However, in the interior work we will find that all these different outer manifestations of the apparatus reduce to three archetypal forms - which we can call the CRUCIBLE, the RETORT and the STILL.
The Crucible is essentially an open vessel, a dish, a mortar, or a cauldron, open to the outside world yet capable of containing material. Substances and energy patterns can be put into the crucible and be acted upon by some agent, and some part of this substance can also be drawn off or removed so enacting a kind of purification.
The essence, however, of this type of vessel and the inner operations undertaken in it, is that it is open. A transformation can be undertaken because certain energies (or impurities) are allowed to escape or dissipate. Heating is not essential to this archetypal alchemical process. Acting on a salt with an acid to produce an effervescence or release of gases, is another outer example of this process, or the slow precipitation or crystallisation of a solid out of a mother liquor.
When we internalise the crucible in our souls we picture a vessel within our being which is open, allowing impurities or unwanted facets of the work to pass out or to dissipate away, as well as substances and forces to enter in from the universal spiritual. In this sense the crucible in our souls is a chalice, the lower part of which contains and holds a substance or constellation of forces while its upper part is open to universal spiritual influences. Unwanted energies can be allowed to safely flow out of our crucible and dissolve in the universal flow, and in the other direction energies can be gathered from the spiritual and allowed to descend to the bottom of our interior vessel.
The Retort in this archetypal case is a sealed flask. In this interior work we picture our soul as entirely sealed off from both the outer world and the universal spiritual realm. When we undertake this exercise we must have everything we need within the sphere of our inner retort, and for the duration of this work we are entirely self-contained and rely on inner change to take place within the components or forces we have within our being at that time. We have to work to bring about a transformation in these inner patterns, without relying on external forces. It is thus very important if we are to undertake such interior exercises in a positive way with any hope of any satisfactory results, to prepare ourselves and place in our inner retort all the energies and symbols that are necessary for the process. Thus working this particular exercise requires some degree of preparation.
The retort exercise is especially valuable for working towards the interior synthesis of polarities. We place the polarised patterns of energy bound up, say, in some particular set of symbols, into our interior flask, seal it up, and allow them to fully unfold, interpenetrate, and come to a new synthesis. The most common symbol of this in alchemical writings is the man and woman in a flask, uniting and giving birth to a child. So the obvious forces to work with through this exercise are our masculine and feminine components. Through putting these patterns of symbolic energies into our inner retort and calling up the manner in which they manifest and resonate within our beings we can bring about an encounter with these psychic components and make them meet in a positive way. Other polarities we might try to work with are our logical thinking and emotional intuitive facets, or body and spirit, even our awe of the spiritual light and our fear of the deep darkness of matter, or the processes of life and death, and growth and decay.
The final interior vessel to consider is that of the Still. When we try to experience our inner world though this symbol, we should have a sense of extracting an essence out of one of the interior processes, purifying and gathering it within our being so that it becomes an inner source we can touch upon at will. This alchemical operation to some extent corresponds in our everyday outer consciousness to the way in which an experience of coming to an understanding of some aspect of our world can entirely transform our way of interacting with it. For example, our initial reaction to a new piece of technology or an unfamiliar task, is tentative and fraught with difficulties we project upon this device or task. If we can eventually understand just how the device works or gain a picture of the movements needed to accomplish the task, then our way of using the device or of undertaking the task becomes entirely transformed.
Similar processes take place in respect to our interior life through the exercises of inner distillation, though this works on a more subtle plane. Here we take some particular positive quality of our being, such as our creativity, or our sensitivity to others, or our ability to think deeply and clearly, and we find some symbols that capture (or at least envelope) the essence of this quality. We then place these into our interior Still and in our meditation begin to allow these symbol patterns to flow together. At some point in the inner work, we should sense some essence of this process begin to rise out of and separate itself from the specific symbols and feelings connected with this quality. If we encourage this process we can have the inner experience of elevating this essence and allowing it to collect in the upper part of our soul. It then becomes a Tincture.
If, say, we choose to work upon our creativity through this exercise, we place into our interior Still, our understandings of the source of our creativity, picturings of our previous creations or our work in progress, memories of the emotional currents associated with our creative experiences, more universal symbols of creativity, and so on. In a meditative work on this facet, which will take many sessions to bring to fruition, we evoke all this material in our interior Still and attend closely to the processes and changes taking place there. For example, at one point we will experience the 'polarity flipping' of various symbols. We might, say, initially believe our creative impulse lies entirely in the quest for some ideal form, and experience this ideal image flipping (instantaneously interchanging) with its antithesis, some ugly shapelessness, or cycle of metamorphoses, producing disturbing patterns within our being. This stage will eventually resolve and we will find some symbol or feeling-perception that captures the essence of our creativity (or whatever we have chosen to work with) emerging out of the meditative material. If we nurture and sustain this essence, then we can allow it to rise up within our soul and we will feel it remaining as a kind of tincture in our inner world.
