Above drawn is a curve, say mk spire, showing an inward going line, which can describe any bilateral psychological process in the form of its timeline explaining its properties in a more in-depth way than a daily linear timeline. The top-most marking is the first one following by others with a predicted trajectory to the centre(unknown) because it's the end, which is also unknown until the curve is completed to the point that may very well be not the geometric centre. It is denoted as the slender distinct arrow in the above drawing. Theoretically, these sorts of shapes mostly have undefined ends but we can still find shapes like these around us everywhere^[1] certainly ending somewhere (beyond the scope of this post too). For example, a common spiral is mentioned below-   

Though the drawings here are quite uniform and symmetrical, they can be otherwise in both aspects and also with variable and inconsistent centres or ends. For instance, the thickness can be variable in any segment of any part. The Participants(of the process) are involved at any point on the curve and/or along it, depending on their degree of involvement. The markings signify the points of time for the many measurements of duration in terms of angle^[2] w.r.t the eccentric curve they are marked on. For instance, if in the above drawing, 90𝆩 on the outer curve means one day, then a full round turn comprises four days.

The key gains from drawing such a timeline are many, some of them are-

• The duration of the process depends on how many turns the spire makes, the longer the duration higher the number of turns.
• More the number of turns, the more packed the drawing becomes. The hindrance at any point can be observed through the relative thickness between the preceded and succeeded turn from that point.
• This symbolizes the increasing amount of stress and tension as we go along the process.
• In human life processes, the end and the converging point (centre) are always slightly different, tending towards each other. It can be considered like the cases of ideal and real.
• The significance of the angle used here as the parameter to measure time is because of its ability to be independent of the process's length and progress. It also marks the vastness of time through the representation of its mere repetition, again and again.
• The current shape shown here is the simplest form of a bilateral process, of course, there are many other elements present in the real scenarios and they all have related derivative shapes clinging to the main curve. It can roughly be imagined through the image posted next.

Symbolically, if the nature of the process is defined by one party throughout, the other party moves along the process voluntarily with every degree of rotation in accordance with the provisions of the organising party. However, the movement for the experiencer is rather three-dimensional. As he keeps circling through time over numerous angle spans, the spire keeps getting longer, surfing towards the distant result that is predominantly dependent on the penultimate turn taken at the moment of any point of time. The process tends to form an anti-golden spiral.

For instance^[3]-

So why is this better than the daily linear timeline-

Because it's more realistic, like a clock. A psychological process experienced at the receiver end is never linear, it gets unorthodox with respect to all the previous steps. At the time of completion, the spire just stops at a point, but when it goes on for several clock rotations, the endpoint gets further stretched, the space further congested, hence tensed and often confusing if the big picture gets blurred to the experiencing party at that point of time. For others, in two dimensional, apparent and common.

The process also makes sense because it also gets its explanations from the Fibonacci sequence formation when represented in 3D as the golden spiral^[4]; as the progress in the timeline in a psychological process at any time is the sum of previous progress, a cumulative just like the Fibonacci pattern and hence a spire. 

Another key point here is the straight line.

The spire tends to become a straight line when the progress tends to become negligent but the process is still active. The inactivity doesn't stop the process but rather puts it on a prolonged delay in the end. As long as there is a direction to the process, it continues to exist.

The straight line is theoretically non-ending, directed towards the predicted end, which is still unknown.

   Right from the very DNA to the Milky Way galaxy, from various natural archaeological shapes to cross-sectional analysis of structures over a range of sizes, the spiral trajectory (logarithmic in many cases) is the most common pattern of nature. One of the reasons behind it is the thermodynamic feature of this path which ensures maximum entropy (a measure of randomness). It gets way better in the mathematical features but in layman's terms it can be understood by observing a pile of dried leaves passing in the wind, or the formation of miniature tornadoes of dust in a messy room when several fans are switched on.

   For any enclosing trajectory, the angle w.r.t to any pivot (real or virtual) is observed to be a better guide of direction than the vector direction of the path. The pointy Vertex of it, longing towards the end and the continuous changes in the direction of angles it defined by the inward motion of the curve at the start of the process, like the right-hand thumb rule we use to find the direction of various fields when we deal with electricity. In a way, the entire trajectory can be observed as a charged body.

   The colour of the process, since it's a human psychological process, also plays a role in imparting additional knowledge. An example is seen in the images above. More on it later.
