Making your mark on the world is hard. If it were easy, everybody would do it. But it's not. It takes patience, it takes commitment, and it comes with plenty of failure along the way. The real test is not whether you avoid this failure, because you won't. it's whether you let it harden or shame you into inaction, or whether you learn from it; whether you choose to persevere.
Nobody trips over mountains. It is the small pebble that causes you to stumble. Pass all the pebbles in your path and you will find you have crossed the mountain. The mind does not create what it perceives, anymore than the eye creates the rose.
Know it for certain that without steady devotion for the Guru and unflinching patience and perseverance, nothing is to be achieved. You must have strict morality.
