Any movement, whatever the direction or course is significantly defined by how we view. That we have to chart a path and perhaps even create the territory has to be matter for consideration. This is even more so if we move with a view. Parameters, of any nature, become indispensable with the traversing of the ground we choose to tread. When it comes to the body, such goalposts are often described in terms of specific loci. Thus our reading of definite sensations. The quality of our interpretation however, is likely a separate movement.
The common factors as alluded to above are the spanning of ground coupled with our measure of where we stand. There is a likelihood that habits are a means for assessing such passage. Take the habit of drinking tea for instance. When we drink tea, we assess our ability to breath and swallow, and our capacity to feel. The taste, the smell and the fullness are in many ways, feelings, and this implies that we measure against their absence. The swallowing confers a locus through which the other sensations are viewed.
The interpretation of the anchoring and the viewing is likely also a sensation, with its locus being the quality of interpretation. The pervasiveness of habits might stem from the vastness of the range of possible quality. In simpler terms, our habits while being anchored in the body are in play outside it.
Hence the import and influence of habits. The closer the anchor and view to the body, the more the certainty. Perhaps it might be reasonable to suggest that habits give us a sense of certainty. Therefore, they confer routine and comfort in the face of all that we cannot and do not know.
