The third day of the week focuses on the idea of tiferet - the harmony that comes when all things are balanced. Harmony in the area of loving-kindness - an important and occasionally subtle idea.
Devoting ourselves to caring for one another can drain our resources for self-care. When we work in a caring field - and probably every job today has an aspect of caring for one another - we can over-extend at the expense of other areas as well.
To find harmony as we care and devote ourselves to kindness is to understand that there is such a thing as too much. Giving until it hurts is not a solution.
Give, take stock, and take care, so that we can continue to be kind and loving another day.
