"God weighs every person differently"

"The question is asked about the universal longing and aspiration for peace of mind and heart.

There are those who do not reach too high a decree of tranquility.

It is taught that God weighs every person differently.

Some are judged according to their achievements and others by their failures.

No one is weighed in the balance by the peace of mind he attained, but rather by the nature of his struggle and what was won in the battle."
