This is very ancient material and is the basis of the majority of the belief systems on this planet past and present. Without getting into the specific belief system side of it as it is so voluminous, I will instead focus on the physical - how it affects you.
The one that is two splits into positive and negative, earth and solar, male and female. The one is still there but so are the two. The one can be seen as the spine. The two can be seen as the arteries of Kundalini the Ida and the Pingala. On the caduceus this means that Spine = the staff and Ida and Pingala = the snakes climbing the staff.
As the snakes encounter specific areas on the spine that correlate with specific human experience i.e. emotional experience or survival experience or communication experience or reproductive experience and many others they will resonate with these experiences and if it (the experience) is balanced they will move on to the next area or repository of specific experience = chakras.
As these activate, meaning, become Kundalini active, the serpents make their way to the top of the head the fontanel. Extreme feelings of movement and sensation that is outside of your volitional control can be felt. As well as a myriad of feelings that will accompany this ascent. This can be extremely rapid or gradual and is unique to the individual.
Sometimes one side will reach the top before the other. This side will rest at a certain chakra - this can be indicative of an imbalance and as it is restored to balance the energy moves to the top and the circuit is completed.
Keep looking up to the brow of points about an inch and a half above the bridge of the nose. Eyes slightly crossed and looking up. It is there you will witness your in-light-in-meant, enlightenment. The Golden White light.
Even after the less subtle phenomena of bliss and joy and healing and visions occur, keep your practice strong - meditate and pray and serve and practice. All within the context of love. This is a choice. I can recommend you go this way, but it is your choice, you are not bound by my wishes. This path or choice of love is the safest way to begin this journey in my experience. Other challenges will present themselves but with the strength you will have garnered from the practice of a love based format you will be much more stable and able to walk your way through any obstructions or challenges on your way.
This is the Holy Grail that so many seek. And all who read this are worthy of this journey.
