I will try to expand this answer in the future as I know that the sources are quite numerous.
One such book explaining why one must make Aliyah for Kabbalistic Halachic reasons is a book aplty named Lech L'cha. It was written by a Rabbi in South America who moved his entire congregation to Israel sometime between 1948 and the 1970s.
Some of the many reasons given for the need to make Aliyah include:
- One must wait for the Moshiach at the place he will arrive, and not stay at home, showing up late to the Moshiach's corenation. This is an argument against those who refuse to come to Israel until after the Moshiach has arrived.
- Prayers said outside of Israel strengthen the angels of the Non-Jewish nations in which those prayers are said, thus increasing the suffering of Exile.
- The concept that the Shechina is in Exile along with the Jewish People to help comfort them, and so one is obligated to return to Israel so that the Shechinah may return with you.
- An obligation to believe in the Goodness of the land and to not commit the same sin as the spies in the Desert.
He then concludes his arguments by saying:
The Privilege of Being Pushed Out
Whoever has merit, therefore, will be privileged to hear the Heavenly
voice crying out, Lech lecha – Go, you, get going from your country
and birthplace… to the Land. As is written in the Medrash HaGadol on
Parashat Lech Lecha: R. Yehuda son of R. Shimon said in the name of R.
Hanina: This is how G-d appeared to Avraham, like one who pushes his
friend to "get going." From this we learn that if one who has merit,
he will experience something "pushing" him out of the Diaspora and to
the Land of Israel.
And then ends with a bracha for one to say every day which is translated as thus:
May it be Your will, the Lord my G-d and the G-d of my fathers, that You might help
me, for the sake of the glory of Your name, to
love the Land of Israel with all my heart - every season, every day,
and every moment. May I similarly always fulfill the commandment of
living in the Land of Israel, as is written, You shall dwell in it.
And may I always take delight in living in the Land, and do so with great
passion, as a child who misses his mother - just as Avraham
Avinu, peace be upon him, longed for the land. I too, one of his
offspring: please grant me the merit of this trait as well, so that in
its merit, I shall be atoned for all my sins and iniquities, from the
day I was born until today, and even for those in my previous
incarnations, and even for my having disdained the Land in the desert
during the Sin of the Spies – as is written, "They despised the
beloved land" – and having thus caused a weeping for generations.
May the difficulties of the journey to the Land of Israel be a 'ransom of my
soul,' as is written, "For Your servants hold her stones
dear, and cherish her very dust." And grant me the merit of always
living in the Land until the arrival of the Righteous Redeemer, may it
be speedily in our times, Amen.
And enable me to adhere to the Land with joy and good-heartedness, and may this
verse be fulfilled in me: "Who is like
Your people in Israel, one nation in the Land." And may the light of
the upper holiness of the Land of Israel shape my soul, my spirit, and
my life to rise up in sanctity, and to be counted and seen there
before the Lord G-d of Israel, with the entire community of Israel.
