It is not enough for the Jew to rest content with his own spiritual ascent, the elevation of his soul in closeness to G-d, he must strive to draw spirituality down into the world and into every part of it – the world of his work and his social life – until not only do they not distract him from his pursuit of G-d, but they become a full part of it.
~ (R. Menachem M. Schneerson)
