The Seventh Day of the Omer makes one week, and completes our first cycle through the first of the sefirot, Chesed, loving kindness and compassion.
The seventh spot is Malchut, literally translated as Sovereignty, the exercise of will on reality. When thinking of the divine this can be the application of the infinite in creation, when thinking of us, it can be the completion of a balanced and well thought out action, as well as the accurate assessment of our current situation.
In order to exercise our compassion, we must see the needs around us, evaluate them realistically, and then meet them with a balanced approach based on all our other values.
See needs, and respond with balance, in order to complete a kindness.
Happy ending of Passover and happy counting!
