A Brief Biography
Rebbetzin Chana Scneerson's biography, which includes her account of her husband's heroism, arrest and passing.
It’s G-d’s world. Everything He gives is good, the sweetest good.
But it is often a good far too great for us to understand. We imagine it is not good, because that’s the only way to make sense of it with our small minds.
Yet the truth is, He gives us all the good we can handle. If we could take more, He would give us that as well.
Trust Him. Trust is the capacity to embrace blessings larger than your mind can hold.
