Lechatchilah Ariber
The Rebbe Maharash taught: “The world says, ‘If you can’t crawl under, climb over.’ But I say, Lechatchilah Ariber – ‘At the outset, one should climb over.’” A person should not wait until the lower path is blocked before he rises above an obstacle. He should meet it from the start by going over it.
