Gratefulness is the key to a happy life that we hold in our hands, because if we are not grateful, then no matter how much we have we will not be happy—because we will always want to have something else or something more.
When I am dead, come to me at my grave, and the more often, the better. Whatever is on your soul, whatever may have happened to you, come to me as when I was alive and, kneeling on the ground, cast all your bitterness upon my grave. Tell me everything and I shall listen to you, and all the bitterness will fly away from you. And as you spoke to me when I was alive, do so now. For I am living, and I shall be forever.
