A fundamental teaching of the Rebbe:
You must know that you are in this world with a divine mission. And that everything that exists and ever existed depends on you fulfilling that mission.
And if any mountain should stand in your way,
Or an ocean blocked your path,
Or anything that might stop you from achieving your goal,
You must know that you are on a mission from the Creator of heaven and earth.
Therefore, it is absurd for any of His creations to stand in the way of your mission for which He created you.
Except that those may not be obstacles, but vital elements of your mission, designed to lift you high, and higher.
