In all you do that you value, in learning what you want to learn, you demonstrate perseverance. Very little can be accomplished unless you persevere. To learn what you must learn to replace illusion with Truth, requires great perseverance.
Your understanding is always based on the thought system to which you adhere. You never learn on your own just as no decisions are made in isolation.
You learn and you decide with the help of one of two possible teachers: the Holy Spirit or the ego. There are no others.
