There are also many similarities between Erev Shabbat preparations and those we should focus on everyday in preparing for the World to Come:
• We work within a limited time frame & avoid wasting time,
• Constantly build, plan and prepare,
• Focus our activities and attention towards a future-oriented-goal
Shabbat enables our Divine soul to be freed from its exile to live in total connection to G-d. The Arizal teaches that on Shabbat we gain a sense of unity from receiving our additional soul. Though Adam HaRishon was driven out of Gan Eden, a part of his soul remained there. On Shabbat, G-d releases that part of his soul and gives it back to man. Thus, on Shabbat we are essentially given the opportunity to return to Gan Eden.
