F=mA(Force = mass x acceleration)
As there is an inverse relationship between mass and acceleration, mass could be interpreted as the tendency to stay in the same space. You might say larger mass increases attraction, and this is true in a way, but what you are attracting is objects of a similar nature, in similar space, to what currently is, and that may not be your preference, just where you happen to be. Lower mass and higher acceleration is better for unpreferential spaces. Higher mass and lower acceleration is better for preferable spaces.  Acceleration is increased through going within, or not actively moving outwards and partaking in actions based on intentions; this is also assisted by creating space between you and the objects in your reality.
Objects exist in space. To give space between yourself and the objects in your reality is to allow freedom of change for those objects. Objects inherently fall into place based on the nature of the space, so allowance for change of objects means that you are open to change in the space that you occupy. Intentional actions create lots of outward momentum, and since reality is INHERENTLY circular, this creates many large circular loops, thereby increasing mass, thereby increasing your tendency to stay in the same space. Losing intention is assisted through decreasing the amount of attention that is focused externally. Not paying attention to external happenings, and not having intentions in relation to externals, creates space, gives the external freedom of motion, which increases your tendency to change the space you occupy, or increases acceleration.
This increased acceleration allows for greater freedom, through greater allowance, but there remains the issue of individual flavor, personal preferences. Whatever mass you do have, and there will always be mass, will have a certain signature to it. This signature is its tendency towards some particular space. Intention, particularly intentional actions, creates mass, whose signature is of its own essence. Its essence is defined by the space it occupies, or the circumstances surrounding it. So, through focusing on things and acting out intentions that are consistent with your preferences, you work those preferences into the signature of your mass, which is your tendency to occupy a certain space. Through, in non-preferential circumstances, losing focus and intention, you remove those from your mass-signature, thereby reducing its tendency to be a part of your reality. Simultaneously, this non-intention and non-focus increases acceleration, which increases your ability to shift through spaces.
