The Opposite of Happiness is Heresy

Happiness is the result of the Jewish perspective on creation.
"He who is grieved and laments
demonstrates that he is undergoing some hardship and suffering,
and lacks some goodness;
he is like a heretic…"

Now, when a man will contemplate in the depths of his understanding

וּכְשֶׁיִּתְבּוֹנֵן הָאָדָם בְּעוֹמֶק הֲבָנָתוֹ,

and will [moreover] picture in his mind how he comes into being ex nihilo at every single moment, so that he is affected at every moment of his existence by G-d’s wisdom,

וִיצַיֵּיר בְּדַעְתּוֹ הֲוָויָיתוֹ מֵ"אַיִן" בְּכָל רֶגַע וָרֶגַע מַמָּשׁ,

how can he entertain the thought that he is suffering,

הַאֵיךְ יַעֲלֶה עַל דַּעְתּוֹ כִּי רַע לוֹ,

or has any afflictions related to “children, life, i.e., health, and sustenance,”

אוֹ שׁוּם יִסּוּרִים מִבָּנֵי חַיֵּי וּמְזוֹנֵי,

or whatever other worldly sufferings?

he who is grieved and laments

וּמִי שֶׁמִּתְעַצֵּב וּמִתְאוֹנֵן –

demonstrates that he is undergoing some hardship and suffering,

מַרְאֶה בְּעַצְמוֹ שֶׁיֵּשׁ לוֹ מְעַט רַע וְיִסּוּרִין

and lacks some goodness;

וְחָסֵר לוֹ אֵיזֶה טוֹבָה,

he is (heaven forfend) like a heretic, who denies G‑d’s omnidemonstrates that he is undergoing some hardship and suffering,presence.

וַהֲרֵי זֶה כְּכוֹפֵר חַס וְשָׁלוֹם
