This adjustment can be an intentional elevation if the space’s energy or it can be a like step down. The effect is both internal and external, as what you breathe changes you, so the same is true of your space.
The act of attempting to manifest something different requires a shift in circumstance. Fumigants are a part of this process.
Consider the internal and external effects of all that you utilize. For instance, some of the basic resinous ingredients one might encounter are Dragon’s Blood, Copal, Frankincense, Myrrh, Benzoin, Storax, Piñon, Pitch, Gum Arabica, and Mastic. Each has a different impact on the environment and the spellwork which springs forth by extension.
There are subtle and overt differences to be sure, so when burning each of these materials, I would suggest contemplating your experiences to see what your chosen ingredients bring to the table. Each of them will be different, and some of this difference is down to the nature of the plants themselves. In addition, your internal state will direct the flow and experienced changes.
This extends to any materials that you smoke as well. If you’ve got a vaping habit, for instance, consider what these inhalants do to you. If they make you jittery, then they can be used to add force and a sense of urgency to the work. If it’s calming & introspective, then this can add a clarifying component to the ritual that can then impact how your spellwork manifests itself.
This is a fascinating aspect of “flow”, and this is why there’s such an important connection between Fumigants and Serpent sorcery. Spirits of this kind work within the flow, and so must you.
