There are certain words bandied about by esotericists and new agers which will grate on the ears of someone trained in the physical sciences. Because therein their use is specific and defined. If you talk about a vibration to a physicist, chemist or engineer it has a very contained meaning. If you say the vibration of a new age it sounds like poppycock, yet people will accept informal “only good vibes, man”.
It is common parlance in esoteric circles to talk about the astral plane, the mental plane and the buddhic plane. Plane to a scientist refers most often to a two dimensional surface or cross section, there are planes of symmetry about which reflections can be made. The misuse of language appropriated by science is a real barrier to any acceptance of esoterica in the mainstream scientific mind, a real turn off, a deal breaker and a red line.
If you speak about someone being polarised emotionally that has no defined meaning. If, however, you describe someone as governed to a large part by their emotions and emotional reactions that is more acceptable. Soap operas are popular because many like the emotional drama as it reflects their lives and how they pan out. In esoteric parlance the majority of humanity is “polarised” on the emotional/astral plane.
Others are preoccupied with body, form and fornication. They are governed by physical sensation, hormonal response, instinctual behaviours and sexual urge.
Those more detached and less dominated by emotion could be said to be governed by mental or thinking process, these can be straightforward or highly abstract.
We might then loosely talk of three moods or modes of consciousness, carnal meaty, emotional and mental. In esoteric speak the physical plane, the astral/emotional plane and the mental plane. There is no plane simply a state, a mood, a flavour of consciousness where the being’s consciousness mostly is. It is possible to move between flavours. A simple act experienced by a detached mental type could cause an upswelling of emotion.
If you are often angry then you are governed by emotions. There is a lot of anger in the middle East just now, a lot of hot angry heads.
In esoteric circles there are the so called buddhic and atmic “planes” which are more “rarefied” and “above” the three “lower” planes. The buddhic state of consciousness is governed by intuitional mind {and heart}.
The aim of rāja yoga is, in one sense, to try to rise above the mundane, emotional and the pettier aspects of mind. The being then “spends” more time free of wild emotional swings and the desire for physical and sexual gluttony. We might speak of individuals who are largely physically governed, largely emotionally governed, largely mentally governed and largely intuitionally governed. {The intuition here differs from mental guesswork.}
This last paragraph does not use nomenclature which belongs to science. Instead of “plane” we are framing a loose description of a state or type of consciousness. No dimensionality is implied. An ordering, perhaps evolutionary is. The consciousness is increasingly expansive and inclusive as effort is applied and mind opened and broadened. One is not dogged by the incessant unwelcome boners of the physically governed and can allow consciousness and awareness to elevate above the belt and emotional storms.
In the blue books opus By Alice Bailey and Djwhal Khul Shamballa is mentioned as a “place” where the so-called spiritual hierarchy hang-out and meet. Human beings who have watched too many Raiders of the Lost Ark and Tomb Raider will be prone to imagine that Shamballa is a place with perhaps secret entrances. They will look for the kingdom of Shambhala referenced in a special scroll of Kālacakra tantra. The insistence on verbatim and dead letter reading causes people to seek out the resting place of Noah’s Ark. Maybe people are unwilling to accept the prevalence of metaphor and allegory in parable. It seems to me Moses parting the sea is more metaphor than physical “plane” reality.
In the works of Kuhl he mentions that the so-called maters can be “found” high up on the mental plane, near the buddhic.
In other words, people who are large mentally and intuitionally governed might be able to “contact” the masters.
Perhaps Shamballa too is a state of awareness, a level of consciousness and a thought form in which these evolved beings congregate from time to time. When one has risen above and expanded consciousness one might be able to build the Shamballa thought form and “go” “there”.
