Most of us have had the experience of knowing something without actually internalizing it. You know the statistics about smoking. You know you should exercise. You know that the difficult situation you’re facing will eventually pass. But knowing a thing and living inside that knowledge are two very different states of being — and that gap is the distance between the life you’re living and the one you could be living.
Today is the first day of Rosh Chodesh Adar, the 30th of Shevat. Tomorrow, the month of Adar officially begins. Adar is the month of Purim, the holiday that celebrates the miraculous salvation of the Jewish people from Haman’s genocidal decree in ancient Persia, as recorded in the Book of Esther. It is a month that arrives carrying one of the most quoted declarations in Jewish tradition. The Sages proclaim, “When Adar enters, we increase in joy.” It is recited and celebrated each year as the calendar turns and Purim approaches. But behind this short, familiar teaching lies a question that cuts straight to the bone.
The Hebrew word the Talmud uses is mishenichnas — “when it enters.” Not misheyatchil, which would mean “when it begins.” Every Hebrew month begins. The clock turns, a new month starts, and life goes on. So why did the Sages specifically choose the phrase “when Adar enters?”
The Book of Esther describes Adar as the month that was transformed from sorrow to joy, from mourning to festivity. The Hebrew phrase in the verse for transformed is v’nahafoch hu — it flipped. Not just improved, not gradually better: flipped. The same empire, the same written decree under Persian law that famously could not be revoked, the same enemy wielding the machinery of the most powerful government on earth. It all reversed in a single month.
That is the backdrop against which the Sages make their announcement about Adar. And yet year after year, people hear the teaching, nod along, and walk into this month feeling exactly the same as they did in the month before. They know Purim is coming. They know the story of Esther and Mordecai. They know God runs the world. And they feel nothing different.
Which brings us back to the word mishenichnas.
Rabbi Shmuel Silber draws a distinction that reframes the entire teaching. The Talmud doesn’t say when Adar starts, he explains, because Adar starting is automatic — the calendar advances whether you’re paying attention or not. But Adar entering — mishenichnas — is something different altogether. It is not the month entering the calendar. It is the message of the month entering you.
The Sages’ declaration is a challenge dressed as a celebration. It is asking: has Adar entered you — really entered you — or is the message of the month something you just know about?
And what is that message? That the story is never over until it’s over. That a decree already written in permanent ink can still be reversed. That Mordecai and Esther looked at an apparently locked situation — a death sentence for every Jewish man, woman, and child in the Persian empire — and refused to accept that the final chapter had been written. They fasted, they organized, they took political risks that could have cost them everything. They moved as people who had internalized not just that God exists, but that with God in control, anything is possible.
The Sages are not instructing us to turn on the happiness because it’s Adar. Forced emotion is not joy; it’s theater. What it is describing is what happens when you genuinely absorb the truth that your situation is not fixed, that the same God who reversed the decree of Haman is the God of your life right now. That knowledge produces simcha, real joy, almost automatically. Because a person who truly believes that nothing is locked doesn’t have to manufacture hope, they already have it.
That is why Adar enters rather than begins. A month that merely begins is an item on the calendar. A month that enters you changes you. And a person changed by the message of Adar doesn’t walk around performing happiness — they walk with the unshakeable confidence of someone who knows that circumstances can flip in ways no human strategist could have scripted. And this brings genuine happiness and joy.
Mishenichnas Adar marbim b’simcha. The month has entered the calendar.
The only question is whether it has entered you.
