For each week’s Sefirah you can ask yourself on this day of Yesod, have I done the inner work needed…to look at my doubts and my determination?  At this level of Yesod in Yesod we also have to look at our relationship with others—are we in consonance with them or struggling with them? As Moses held his arms up during the battle with Amalek they finally tired and two compatriots came to his support—literally—each one supporting an arm.  The image of two men supporting Moses’ arms is there to enforce that in the battle for determination over doubt we need the support of others and today is a day to reach out and ask for that support and encouragement.
