It’s only through daily persistent efforts of our training and meditation that we can attain these benefits, yet once attained they become a part of you as a person and continue to endure.
The particular practice you do does not matter so much, it is more that it fits with you and your purpose, and this may change over time. Having strong values at your core and the ability to persist on your path will allow you to develop these indestructible skills that enable you to have a better way of life. Enabling you to live in a that is more peaceful and filled with insight and onward growth.
