Conscious Volitional Attention
Enlightenments real foundation. It starts here!
The cornerstone distinction of being a human is free will. All other animals don't have this. Your conscious volitional attention is the basis of your free will. This can never be taken from you unless you are sleeping, knocked out, drugged or you have a severe psychological condition. Hence pillar No1 is Correct Presence Practice is the foundation of real Enlightenment.
To be aware of the Enlightened state requires the use of your volition so it is sensed and experienced. It is the action of your will to check that you are somewhere within the 4 steps of Correct Presence Practice. Applying this attention takes mental effort, motivation and desire. Yes, as one habituates the higher phases of Awakening the speed, instantaneousness, stability and durability of the process get faster. It also becomes visceral within your body as your neurology is activated and becomes capable of holding everything from fight-flight to the Divine yum-yum at the same time.
Visceral action not mind created
Beliefs and Mindful creation is delusional
The core reason Correct Presence Practice is so effective is it is based in your physical body. Preferably from the sternum, heart, and below. This enables the neurology to be activated. This also means one's awareness includes the heart and solar plexus brains (neural plexuses). Neuroscience has only recently been studying the 40,000 neurons found in the heart. The picture indicates their position in the Superior Vena, left and right Atrium indicated by the yellow dots. The impact of these neurons is massive as they were formed first in the womb before the cranial brain. 
Therefore these heart neurons will likely contain many primal baseline memories as the fetus starts to grow. Unfortunately, this means they store traumas that are extremely difficult to shift. These neurons capture primarily our mother's unconscious modus operandi. Pillar No5 of the unconscious mind strikes again. This entire process is all 100% unconscious so once we reach age 7 and above and our ego is formed we then have our ugly base of garbage to work through. Hence the entire base of modern psychology revolves around our first seven years of life.
Working with the heart-brain is an advanced topic for coaching and the Mastery club. The heart-brain and videos discussing how to explore it are in the Mastery club for the group to research. Often the issues stored in there don't need to be addressed until one is in or beyond Abiding Awakening phase 3. This is a topic of ongoing research and observation by myself. As neuroscience has only just started to examine it, it means there is much we don't know about its impacts. Some ancient cultures do seem to have rituals and processes that involve the heart neurology and healing using that part of the body as a key.
