Just like Hashem told Yitzchok his true place is Eretz Israel, so too, must we all know that are true place is Eretz Israel. In addition we learn from the Avos how to live our lives from Avrohom Avinu we learn that even those that sit and learn, should also go out into the world, reach out and inspire others, and from Yitzchok we learn that even if you one that spends your time going out reaching out and inspiring others you must set aside, time to sit and study Torah.

לקו”ש כה-ב

There are two reasons why somebody would be kind, one out of greatness and power and wealth, where he has the feeling that he would like to share a little bit, there he takes most for himself and gives away a little bit, there is another kind of kindness which comes from humility, where he feels everybody else is entitled, so he takes a little bit for himself and gives away the rest even to somebody that’s very simple, and he’s willing to put himself in danger for that, that was the kindness of a Avrohom Avinu, therefore meriting the two Mitzvahs of the ashes of the Para Aduma and the dirt of the Sota, both representing kindness from humility. לקו״ש כה-ב

Although celebrating with Wine can be a Mitzvah, there is a human element of happiness that comes as a result of drinking wine therefore somewhat limiting its happiness, as opposed to water that doesn’t naturally result in happiness, which they would draw for the Mizbeach on Sukkus . Hashem commanded to do so in happiness, therefore the happiness then is only divine. In addition we draw all the energies and light from Rosh Hashanah and Yom Kippur on Sukkus through happiness where we surround ourselves with it because everything we do is in the Sukka and then we internalize it and bring it to the heart with a Lulav and Esrog.

לקו״ש כד

Although one might feel like we are a very weak and small nation, when Moshe entered the Jewish people into a covenant and oath together with Hashem it was for all the people than and for all future generations bonding them together above time and space and therefore when we learn Torah and do mitzvahs we’re bonding ourselves with all generations making us a very big and powerful and beautiful nation.
