Shakti induces altered states of consciousness by applying magnetic signals to your head.
The magnetic fields get stronger and weaker, mimicking patterns that appear in EEG traces. Although they're still magnetic fields, they are also 'magnetic signals', and that's what we'll be calling them.
The temporal lobes of the brain (as shown above) are the area most likely to produce spiritual experiences from this kind of stimulation, though Shakti can be applied to several areas of the brain. To have such experiences using Shakti, you will need to do your sessions during sensory deprivation (especially silence). Interestingly, laboratory studies have found that the effects are most pronounced during times of geomagnetic quiet. (Click HERE to see the current levels)
This technology can enhance your meditation, Yoga, or other spiritual practice when Shakti sessions are done an so that they end about an hour before your spiritual practice begins. For this kind of Shakti session, you don't need sensory deprivation.
There is more to say about Shakti, but the best way to fully understand what it can do is to read the rest of this page, and check out the online demo for the software, which is packed with information about how to use it, and what kind of effects each signal can produce, as well as how to set up your audio, where to put the coils and more. There are 'quick start' sessions as well as basic and advanced session designs.
Shakti uses audio files to play the signals. The 'sounds' have the same shape as an EEG signal - one whose appearance shows the activation of a particular structure (brain part). The magnetic coils are plugged into the sound card, just like a pair of speakers. When the audio file is played, the coils produce magnetic fields whose shape matches the shape of the original EEG trace. That activates the part of the brain it came from.
When the signals are played and the coils are in place, the coils put out magnetic fields that match the original EEG trace.
You have two of each, one on each side.
On one side, it supports a broad range of positive emotions, such as elation (along with many other functions). It also functions to infuse our experiences with a sense of meaningfulness.
(Based on previous work with the amygdala using it's signal.)
The Hippocampus is a cognitive, or 'thinking' structure.
On the one side, it supports silent, non-verbal ways of thinking, positive thoughts and expectations, spatial perceptions, and several kinds of inner imaging, including imagination, visualization, and pictorial memories (along with many other functions).
On the other side, it supports verbal skills, negative thoughts and expectations, and logical thought (along with many other functions).
Based on previous work with the hippocampus using it's signal.
On one side, it seems to support arousal (including anger, excitement, sexual desire, and a sense of anticipation).
One the other, it supports relaxation, calm, and even lethargy.
Based on preliminary reports from a few people using this signal.
It supports the experience of pleasure, with a special emphasis on sexual pleasure (including Orgasm)
Preliminary reports from a few people are consistent with it's known role in mediating sexual enjoyment.
Even though we can apply the wave forms "symmetrically" (over both sides at the same time), your brain probably doesn't work symmetrically. For example, if you have low self-esteem, you probably use your right side more. If you're prone to irritability, you might be more active on the left side. If you're very emotional, your amygdala's activity might offset your hippocampal activity a bit. If you think in pictures, you might have a busy right hippocampus. If you think in words, you might have a busier left hippocampus.
This means that some session designs may not be as effective as others for you.
The things that affect the way individual brains respond to Shakti often relate to long standing, even lifetime, personality traits. If targeted structure has a history of low activity, the 8 Coil Shakti might produce quite a marked experience for that person.
There is also the recent addition of a signal derived from the Septum, the Brain's "Pleasure center". Initial reports indicate that it's effects are consistent with the Septum's function - the capacity for pleasure, especially sexual pleasure. (more)
What you experience
depends on who you are and how you choose to use Shakti.
