The Rebbe Maharash innovated the concept of "L'chatchila ariber". The approach of l'chatchila Ariber teaches that if we come upon an obstacle to a task we are involved in, or an obstacle to a mitzva or project or good deed which comes our way (or we pursue), we should overcome the obstacle in the most direct manner. The Rebbe Maharash explained that while some people propose that when confronted with an obstacle the best route is to go around, or under it -- and the Rebbe Maharash says: "And I say one has to go l'chatchila ariber [from the start, go over it]."
When You Carry Valuable Merchandise
The Ohr HaMeir says that in life there are certain people who have it easy. Everything goes smooth for them and no obstacles stand in their way. They think that they have reached perfection, they are on top of the world. On the other hand some people cannot catch a break. Every time they make a move something goes wrong. Are they traveling on the wrong road?
The Ohr HaMeir explains with a Mashal. If someone is traveling on the road carrying a sack of wheat husks, his trip is easy. He can travel wherever he wants, for as long as he wants, feeling secure and knowing no one will rob him of his goods. However, if he is carrying a satchel of precious stones he sweats every step, knowing that he is a hunted man.
Dovid HaMelech says in L'Dovid Hashem Ori [Tehilim 27:3] "Im Takum Alai Milchama B'Zos Ani Botei'ach" - if the enemy is constantly attacking me, in this I find confidence. Why? If my path in life was devoid of any value I would not encounter constant resistance from the Yetzer Hara. The fact that there is an obstacle in my path at every turn is a sign that I, my actions, goals, and ambitions are very valuable. So valuable that the Yetzer Hara is throwing all his resources at me to stop from accomplishing my dreams.
