היום ששה ימים בעמר
Today is six days of the omer
A day of foundation in a week of loving kindness
One way I see the first six sefirot, intentions, of the omer week is an alternation between soft and hard pairs. Loving kindness/strength; compassion/perseverance; humility/foundation. The balance is dependent on the aspect of the weekly container.
The hardness of yesod/foundation represents a grounding, a firm connection maintained with the earth. Holding it in loving kindness reminds us not to let that connection tie us down so firmly that we stagnate. We need to be able to take off, willing to learn from influences outside our sphere. The beauty of having a spiritual practice is that we always have a way to reconnect to that supportive yesod space that grounds us.
