When I was a child, I had a very active imagination. Though my bedtime was around 8:30pm, I wouldn't fall asleep until around 11:00pm, as I would be engaging my imagination living out all of my "Jungle Book" like adventure-fantasies. I guess that's why I chose the form Shiva as my main male archetype guide, as I wasn't interested in Krishna's golden crown (though now I under it as Kether or the peacock third-eye), and though Jesus was a fantastic character and a continuing guide, I just could not relate to other Christians. Nonetheless, this use of imagination would be a key to astral projection, channeling, etc., but is only a stepping stone as the adept moves through numerous higher aspects of themselves, known as higher selves, until they have reached the unity of Self, and thereafter realized the delusion of Self as one moves their consciousness to further investigate the formless Shiva (aspects above Kether).
Another simple game I would play as a child, was that I would close my eyes and relax as much as possible by moving my breath around my body to wherever it was required. I would relax so much, and as a child most likely on a bored summer day with nothing better to do, I would have nothing to think about and be quite clear-headed. Children under summer vacation don't have to worry about what they are going to do the following day, they don't have to plan their life, and their probably just looking for the most exciting thing to do in the moment. The same applies to romantic interests, though I see this as easily programmable in children, but I don't think children grown up thinking about engaging romantic interests and formalities. In other words, all theses worries, belief-systems, emotional crap we throw to the back of the mind (subconscious) when we choose to not self-reflect (Self-inquiry, bring light to subconscious, enlightenment) and fully en/lighten up our psychological baggage for the brilliance of the virginal moment, hold each individual back from truly living their true signature. Nonetheless, the unprogrammed child has the ability to clear his head rather quickly, easily, and effortlessly. In addition, it is said by the Taoists that breath-work is simply breathing techniques to help the adept return to normal breathing patterns which we experienced around birth (to be able to breath fully down to the lower dantien).
In doing this simple relaxing game as a child, bringing me to a blank slate consciousness, I would return with eyes-open with such pristine clarity and calm. I would raise my hands to my eyes and watch how I, as simply awareness, held the ability to consciously move the digits of my fingers. The inner feeling that would develop is akin to the character in James Cameron's "Avatar", who switched his awareness from the human-vessel to the avatar-vessel. After the switch, there was that initial reaction of "cool, look what I can do", but then there was also that adjustment period, where Spirit (Psyche) aka Atma (Consciousness) must mold itself with the animal vessel and its numerous senses. Not only must the Spirit engage the animal-vessels interests such as security, sustenance, carnal, etc., but like in "Avatar", the thought-patterns and emotional-energies that complement such belief-systems held by the character are also transferred from one vessel to the other showing karma. Again like in "Avatar", the character was then forced to begin psychological de-conditioning in order to regain unity-consciousness. As an adult practicing Advaita, yes, Oneness is a legitimate experience as the Avatar is the human multidimensional, and beyond all-dimensions, Self. Simply put, as Shiva has taught, the Avatar is the ability to yoke the animal vessel with the higher consciousness, Yoga.
Hence, true-spirituality, are those moments that we are able to let go and be (sat) psychologically in the pristine virginal moment. A few years back, a buddy of mine took me to the shooting range with a 12gauge and 9mm. It was my first time shooting, so I was hoping my buddy would be give me better instruction, nonetheless, what poured out of his mouth was so much more important than properly instructing me on how to hold a gun. As I held that 12gauge shooting these clay discs, essentially my buddy stated, "isn't this great, like time stands still, there's nothing else but you, that gun, the target, like nothing else matters". My buddies words were reminiscent of Rollin's "Harley Davidson and Philosophy". Though I have yet to be on a bike, a childhood dream, my imagination and what I can gather from riding a non-motor bicycle, is that feeling that there is no separation between the spirit-human vessel and the surrounding flowing environment. There are many opportunities for moments as such to arise, but they usually arise when we are fulfilling something that deeply touches the adept.
The practice of stillness, is like bringing a magnifying glass to the moment, and being able to perceive with heightened clarity. Particularly when the adept has done significant deconstruction of limiting-beliefs freeing up the emotional body as felt through the central-nervous system, the moment glows with beauty, where the slightest enjoyments will release the most pleasing hormonal cocktails felt within sensory animal-vessel, leading the adept to realize that not much is required to experience ananda (bliss), and further as such, all is actually sourced from within as the adept gives these moments to themselves, "as within, so without".
That stillness that brings us to presence is the true-art of spirituality, in each and ever pristine virginal moment. The presence brings Spirit to properly align (law of attraction) with the human-vessel, where the human is no longer a product of the monkey-mind dualistic interpreter mechanism (ego), creating divine presence or "as above, so below".
Stillness brings us to, The Avatar Self.
