Among them: One must strengthen one's belief in, longing for and anticipation of the coming of Moshiach, to such an extent that as long as our righteous Moshiach has not yet come in reality and openly, one feels his life is lacking. As Yaakov said, even one hundred and thirty seven years were "few" because the Redemption had not yet actually come.
Further and fundamental: One must increase in learning and spreading the inner teachings of the Torah (and Torah in general is Yaakov's function), oil (secrets of the secrets) of the Torah, in a way that they light "from the opening of the house on the outside," "your wellsprings will spread outward," "until the Tarmudites leave the market."

[This is a reference to the passage in the Talmud that discusses the latest time for kindling the Chanukah lights; the rabbis declare this to be when the Tarmudite merchants would leave the market and no one else would remain outside. Chassidus explains that the word "Tarmud" (the name of a nation) rearranged spells "Moreds," rebel. Metaphorically this means that we will bring light to the outside to the extent of removing all resistance to the Divine. Translator's note.]
