Words are only signifiers of meaning

The meanings of words are not absolute or fixed.
They are quite stretchable, and can range all the way from literal to the abstract.
Words are more like signifiers or pointers.
The meaning understood from a word depends upon the context/subject/frame/theme/topic and the vastness of scope.

You can point your finger towards a leaf in a tree,
But if the moon is in the same line, you may also be pointing at the moon.
Similarly, the range of the signified meaning is all the way from the immediate to its most far out abstract.

For instance, the word emptiness.
In the ordinary practical context, it would point to a meaning of there being no physical objects in a given space.
But in the metaphysical abstract context, it could mean emptiness of substance or essence (which is the truth of the entire manifest creation that appears to us).
Imo there is no contradiction in these 2 meanings derived from the same word,
Just like how your finger pointing to the moon could also be pointing at some other closer object like a tree leaf in the same line of sight.

About Kundalini

I read that there are 3 stages of enlightenment:
# Stage 1: Gautam Buddha is behind you as a shadow.
# Stage 2: The Buddha comes in front of you, and you become the shadow.
# Stage 3: There is no more of you – not even a shadow, only the Buddha is.
(more information is available on this if you google it)

The kundalini initiates all 3 of these stages.
Kundalini is the “ascension energy” itself.
The “returning to source” movement from base to the crown chakra and beyond (not literal physical location, but more in terms of shifting of energy density from gross to subtle).
Spiritual seeking (the true kind) is from kundalini basically.
Kundalini is present in everyone but dormant, that is why this process is called kundalini awakening and kundalini rising.
Though I say “base to the crown”, the actual process is mystical and non-linear, not a linear flow from base to top in terms of physical location.
That is only for the purpose of symbolic representation.
Kundalini is like the stored source energy(potential) that serves as a vehicle to carry you back to source, it is the agency of transformation.

The concept of transcendence and spirituality does not even occur or appeal to someone whose kundalini is still dormant.
A sincere longing and seeking appears only after kundalini awakens.
Else there is no desire or any interest in such stuff, and such subjects.
The longing to transcend is the desire/potential, the force that makes you explore/seek/do sadhana is the kinetic/action.
That dormant potential that carries to the next dimension is the kundalini shakti.

It is like the upward current that carries you to a lower density, as your being receives greater energy.
Higher the energy = lower the density, like the molecules of gases have a lot more energy than liquids and solids.
Going up to lower density planes means, there is new information, new perception, new laws that are intuited, which are all the unfamiliar new terrains that are passed through in this process.
The “dark night of the soul”, is a stage in this kundalini ascension process, especially applies if you move very rapidly.
You can only move as fast as the amount of ‘loss’ you can handle and process.

So to recap the main points:
Kundalini is a symbolic system which represents the power/vehicle/fuel that carries you through the process of transcendence to lower densities planes from your current higher density plane.
This process is that it is highly mystical, non-linear, and beyond our understanding, at a level of mystery that is similar to life, birth, and death itself.
