For any sort of spiritual intrusion, energy loss, psychic attack, or power drain, the first recommended course of action is working with Salt.

Salt, written as NaCl (sodium chloride)*, has numerous healing properties. It is vitally important to our oceans (which make up 75% of this planet), and is representative of the Element of Earth in countless rituals, ceremonies, and religious offerings (Druidry, paganism, etc.). Chemically, it is a balanced and stable compound, and when its chemical bonds break, it releases negatively charged ions. It is part of the mammalian body system, and certain levels must be maintained for heart function, electrolytes, brain chemistry, etc. Magically, it is a great energy neutralizer and banisher, and has been used in House Clearings, Psychopomp rituals, workplace energy-neutralization, and restorative rites.**
Personally, it is one of the best ways that humans can reset and re-balance their own energy fields. Salt baths and salt scrubs are excellent ways in which one can release the tensions and projections of the workday. Many spiritual practitioners also use salt in their own ritual purification baths, both before and after great ceremonies. Salt helps to release built-up energy (whether positively- or negatively-aligned), and can help ground an over-abundance of psychic phenomena.
If you struggle with “leaving work at work (especially if you work from home, i.e., COVID-19 pandemic)” or feeling drained after difficult conversations with loved ones, then try a salt bath or use a salt scrub in the shower. There are many varieties, such as Sea Salt, Himalayan Salt, Hawaiian Black Salt, and regular table salt (without iodine works best), but please make sure that it is sodium chloride (NaCl). It is one of the easiest and most inexpensive ways to restore one’s energetic, etheric, and auric bodies, and can also be good preparation before a Shamanic Healing Ceremony.
*Sodium chloride (NaCl) is organically different from Epsom Salts, which are magnesium sulphate (MgSO4). While epsom salts feel wonderful for muscle pain and spasm, they are a completely different “magickal substance,” used for Auric/Higher Self workings. Sodium chloride is much more effective for the specific uses of neutralizing energies within a home and within a body.
**Note: Salt should NEVER be used in land rituals or land clearings. It damages grass, plants, and soil, and can actually destroy the energetic state of an area (bringing it to “zero” instead of “neutral”; a major distinction).
