It is said that the tzadikim (righteous souls) never have “peace” in this world. They are always in middle of the cosmic battle between Light and Darkness, fighting on behalf of the rest of us.
Thankfully, most of us don’t have to go through a life of unending struggle because we’re not as spiritually elevated as these righteous souls. But what we can glean from their sacrifice is the understanding that every trial that we go through and every test we come up against—whether sickness, loss of a loved one, loss of wealth, or loss of anything else we deem important—is exactly what we need at that moment for our spiritual growth. If we can keep this understanding in the forefront of our heart and mind in the middle of our greatest challenges, then we can anchor ourselves with our certainty in the Light that can carry us through.
