There's also the matter of why the mantra is vibrated a different number of times every day with the planetary squares. I have not thought overly deeply into this specific matter, but I would theorize that it has to do with a wavy "curve" of the energy, if that makes sense. Imagine a 'line' going forward with every day of vibrating a mantra. If you vibrate it more, the line goes up. If you vibrare it less, the line goes down. So perhaps the intentional variation in vibrating the planetary mantra, is to almost "reconstruct" it's vibrational frequency, but on a linear level in addition to just the normal, vibrational level. It would make sense to me why this would add power to the working, compared to just vibrating the mantra for the same amount of repetitions every day.
