This could be translated into ‘heavy’ energy, or ‘stagnant’ energy, energy not moving freely but heavily. accumulating and unconsciously held on to, rather than released with free flow.
Rather than saying negative or ‘bad’ energy, it might be more apt to say that it is just energy that doesn’t belong in an individual’s energy field, that is beneficial to go where it’s more beneficial to flow.
This can be released using a number of techniques and processes. It can be released to water, earth, fire, or air, that can help this flow to where the energy does belong, where it can be utilised well.
Often, we give this hucha energy to the earth, where it can be mulched and ‘mikreed’, as the earth does with our waste vegetable peelings etc, breaking it down into a form that it can be of benefit to the earth, just as compost does, which is why some opening sacred space word speak to the jaguar to assist the mulching and mikreeing, to feed the earth, and assist it grow even more beautiful.
There are also similar theories in ‘shaman’ work that is native to UK (some call this celtic shamanism, but there are other names), where the hucha energy is given to the earth, water, or water.
