Blessing the Good within the Bad

[On witnessing] comets, earthquakes, thunder, or windy storms one says, “Blessed be He whose strength and might fill the world.” [On seeing] mountains, hills, seas, rivers or deserts one says, “Blessed be He who made creation.” Rabbi Judah says: one who sees the Great Sea should say, “Blessed be He who made the Great Sea,” if he sees it at intervals. For rain and for good news one says, “Blessed be He that is good and grants good.” For bad news one says, “Blessed be the true judge.”

The Gemara challenges further: Come and hear a contradiction from what was taught in a baraita: One whose father died and he is his heir, initially recites: Blessed…the true Judge, upon hearing of his father’s death, and ultimately, upon receiving his inheritance, he recites: Blessed…Who is good and does good. Despite the fact that the son alone benefits, he nevertheless recites: Who is good and does good. The Gemara responds: There, too, it refers to a case where he has brothers who inherit along with him.

[The following blessings should be recited] when a person was told that his father died and that he is his heir: If he has brothers [who will share the inheritance] with him, he should first recite, Dayan ha'emet, and afterwards, hatov v’hameitiv. If he has no brothers [who will share] with him, he should recite the blessing shehecheyanu.
To summarize the matter: Whenever a circumstance is of benefit to one together with others, he should recite the blessing hatov v’hameitiv. Should it be of benefit to him alone, he should recite the blessing shehecheyanu.
