brachot 5

saying the shema at night is like a sword of protection


but not everything should be protected against.
Resh Lakish: suffering is a loving rebuke, some things can only be achieved by suffering.

but for R.Yochanan, who would carry his dead child's bone, not all suffering has meaning...


and Abba Binyamin would lie in bed at night, lie in the right direction and say shema.
