Eventually as our practice matures and we have many experiences in faith overcoming obstacles and making changes at the core of our life, our faith becomes more unshakable and it becomes more difficult to become discouraged. I say more difficult but we should never become complacent, as it is always possible to become sidetracked or discouraged. In fact if we take our faith and practice for granted it is most certain to happen. But indeed, over time our doubts do decrease as we accumulate a variety of experiences in our faith and practice. It is our intention to eventually create the kind of firm foundation of faith and practice of the Dharma that removes all of our doubts.
