t doesn't presuppose that the consciousness is Absolute however or that there aren't other consciousnesses, etc.
No, that in itself does not presuppose that. This is the conclusion one draws after analysis of consciousness and matter. If you begin with the premise of the knower, the conscious subject, then you have to infer a second category the 'known' You the knower have objects that are known to you.
So what is known to you? Solids, liquids, gasses, forces, light, energy, atomic elements, senses, sense organs, perceptions, sensations, information, mental states, biological states, chemical states. All of this comes under the category of that which is 'known' If you analyse all these things which are known you will note they all have a common property: change and transformation. We call this the
gunas literally meaning the forces of nature which bring change, transformation and inertia. Thus the entire field of the known is reducible to a single substratum, which we call
Prakriti/Maya Prakriti is an undifferentiated field of matter within which all these entities are abstracted.
The knower or consciousness is not made up of the gunas. It is seeing/knowing/sentience and it is not reducible to the known the gunas. To know a changing principle(matter) requires an unchanging principle. Consciousness is always always constant and this is why you can know anything at all. How do you know that your body changed? You know because you are constant between the two states of your body then and now.
This is why we say consciousness never dies, because it is never born. The body is born and it dies. Consciousness is not under the forces of nature(gunas) it is not composite, it is not divisible, it does not change, transform or evolve, and it is not multiple. It a singular infinity. Hence we say it is infinite, absolute, partless and pure. It is based on this principle that we have created the technology of
Yoga As we know consciousness is pure and cannot be tainted, we know that our habit patterns, our mental modifications, our personalities, our physical and mental blockages are not real. If we suspend ourselves in a state of just witnessing awareness all of these will dissolve.
I remember meditating once at a retreat I had this really sharp and excruciating pain in my leg, but the rules were you were not allowed to move, you had to remain completely still. The pain was absolutely excruciating, but I remained determined and kept meditating. I decided to change the meditation a little, I decided to focus all my awareness on the leg itself. Initially, that was a bad idea because it just amplified the pain in the leg as I became more aware of it(I literally was about to cry lol) However, I remained detached and kept my awareness there and simply witnessing the leg. Something amazing happened after a while, the pain absolutely disappeared, not only that I lost all sensation of solidity in my leg, it felt like it was pure light. I then lost all physical sensation in my entire body. My entire body had become light. This is when I realized the power of consciousness.
PS: The easiest way to reach a state of desirelessness is to not desire such a state to begin with.
It sounds like common sense, but it is not. It is found that when you have an object you desire so much with complete one-pointed focus and devotion, you desire for that object becomes so strong that in itself becomes a meditation. You lose all other desires and thoughts, and then only you and your object of desire remains. Then there comes a point when you disappear altogether and only the object of desire remains(sabija samadhi) and then comes a point when the object also disappears and a complete state of absolute awareness remains(nirbija samadhi)
