Persistence and discipline are qualities that can be cultivated in a person if she truly and deeply desires the end result that she is supposed to 'get' doing what she does.
But in terms of the mental discipline with respect to LOA that you are talking about, I find it to be true, but not in a quantitative sense - i.e. not by increasing the number of affirmations you write or chant or the length of time you meditate - but by increasing and intensifying the desire you have for your end goal |
