Yom Hazikaron

The philosophy of Rav Kook is summarized by the following quote, that describes the Tzaddikim of this world: “The purely righteous do not complain of the dark, but increase the light; they do not complain of evil, but increase Justice; they do not complain of ignorance, but increase wisdom .”
Rav Kook saw the importance of emphasizing the positive that exists in Judaism. He wanted to distance himself from negativity and fighting against bad things. Much more could be gained by focusing on the positive.
This is particularly applicable on Yom Hazikaron when we remember our fallen soldiers. Instead of focusing on the loss and grief, it is our task to gather these sparks of light left to us by our brave heroes. We must convert these sparks to a power of rebuilding and Jewish Unity, and Ahavat Yisrael.
This is very sound advice in somehow learning to take the נגע, the blemish, the negative, and turn it into ענג, a delight.
The sacrifices of the fallen allowed us to have a beautiful homeland, that has grown and flourished in the most miraculous way. May their memory be for blessing.
