it get stronger with regular use and weaker with regular neglect. I think i like that analogy
Indeed, it is.
Yet, we must understand what it truly means to strengthen or weaken. I find it helpful to consider the love/light energy, which flows from the red ray center to the violet ray center.
Strengthening the will might be seen as focusing on one of these centers and utilizing it as designed for its specific purpose.
Conversely, weakening the will could imply a lack of focus and misuse of these centers, resulting in energy blockages and depletion.
