לֹא עָלֶיךָ הַמְּלָאכָה לִגְמֹר, וְלֹא אַתָּה בֶן חוֹרִין לִבָּטֵל מִמֶּנָּה.
It is not your responsibility to finish the work, but neither are you free to desist from it.
Theodor Herzl, "The Jewish State" (1896)
The Jews who will it shall achieve their State. We shall live at last as free men on our own soil, and in our own homes peacefully die. The world will be liberated by our freedom, enriched by our wealth, magnified by our greatness. And whatever we attempt there for our own benefit will redound mightily and beneficially to the good of all mankind.
Rabbi Nahman said in Rabbi Samuel's name: 'Behold, it was good' refers to the Good Desire; 'And behold, it was very good' refers to the Evil Desire. (It only says 'very good' after man was created with both the good and bad inclinations, in all other cases it only says 'and God saw that it was good') Can then the Evil Desire be very good? That would be extraordinary! But without the Evil Desire, however, no man would build a house, take a wife, beget children or conduct business; and thus said Solomon: 'Again, I considered all labour and all excelling in work, that it is a man's rivalry with his neighbour.' (Ecclesiastes 4:4)
Ben Hey Hey says: According to the struggle is the reward.
