Day 37 of the Omer - Rigor towards balance
Gevurah in Yesod - rigor and strength in solid balanced foundations.
While a foundation stands as a symbol of strength the idea of Gevurah as the application of discipline may inform us when we aim for creating foundations the fulfill their purposes.
To use rigor to help create balance requires care.
Still catching up - this applied to the Omer for Wednesday through Thursday.
