The women's tefillos were certainly special because the Rabbeinu b'Chayei tells us that when one davens from amidst his tzaros, there is a greater likelihood that his tefillos will be answered. This occurred in Mitzrayim, they shouted to Hashem from amidst their tzaros, and Hashem accepted their tefillos. As it states (Shemos 2:23) העבודה מן האלקים אל שועתם ותעל ויזעקו העבדה מן ישראל בני ויאנחו, "Bnei Yisrael sighed from the labor, and they cried out, and their cry ascended to Hashem from the labor." The Or HaChaim explains that because they shouted from amidst their sorrow and suffering, Hashem answered their tefillos.
Sometimes people think, "I am going through such hardships, I don't have yishuv hadaas. I just can’t focus on tefillah now." But the truth is exactly the opposite. If you are going through hardships, this can be the best time for tefillah because you can say a tefillah from the depths of your heart.
16. The sefiros are as follows: מלכות ,יסוד ,הוד ,נצח ,תפארת ,גבורה ,חסד ,בינה ,חכמה ,כתר. Yesod, is the ninth. Sometimes, when one is going through challenges, he can't open his mouth to pray before Hashem. He is wrapped in bitterness and can't bring himself to daven. All he can do is shout, "Oy vay!" from the depths of his heart. The Yismach Yisrael (Shemos 2, quoting his father Rebbe Yechiel of Alexander zt'l) writes that this tefillah and moan is also sufficient.
The Yismach Yisrael writes, "This gives chizuk to every Yid when he knows that Hakadosh Baruch Hu sees his troubles and sufferings, and he knows that Hashem recognizes how hard it is for him to pray. Due to his many tzaros and aveiros, he almost can’t open his mouth in prayer before Hakadosh Baruch Hu. Nevertheless, he shouldn't give up. He should shout out to Hashem with all his strength. Even if all he accomplishes with his tefillah is a single krechtz before Hashem from the depths of his heart, Hashem will take into consideration his suffering, low level, and confusion. With Hashem's immense compassion and kindness, He will listen to this moan and save him."
The Maor v'Shemesh (ההם הרבים בימים ויהי ה"ד) writes, "There are times that the tefillah can't go up because the mekatrigim create an iron wall, as it states (Yeshayah 59:2) מבדילים עונותיכם כי, 'Your sins separate...' The Zohar says that the solution is to shout from the depths of the heart, with all one's kavanah – a shout, without words. This is called זעקה and שוועה. The malachim, the mekatrigim, don't know about this tefillah; only Hashem Himself knows. Hashem listens to this shout because it was emitted with truth and from the depths of the heart, and Hashem answers this tefillah. It is a more significant tefillah than a tefillah said with letters and words, which the malachim understand and can be mekatreg and preventing. This doesn't occur when one shouts out to Hashem without saying words. Only Hashem, Who knows man’s thoughts, understands, and Hashem will fulfill the desires of his heart."
Kedushah
Choshech, darkness, was the ninth plague. It is known that the ninth sefirah is called Yesod, which is associated with kedushah, tznius, pure thoughts, pure eyes, and the like.
It states (10:22-23) וַיְהִי ָּׁמ ָיִםהַש עַל יָדוֹ אֶת ֶׁהמֹש וַיֵּט יִשְׂרָאֵל בְּנֵי וּלְכָל ...יָמ ִים ֶׁתש ְׁלֹש מ ִצְר ַיִם אֶרֶץ בְּכָל אֲפֵלָה ׁ ֶ ךְחֹש בְּמוֹש ְׁבֹתָם אוֹר ה ָיָה, "Moshe stretched forth his hand toward the heavens, and there was thick darkness over the entire land of Mitzrayim for three days.... but for all Bnei Yisrael there was light in their dwellings." This plague brought on a contrast. It brought darkness for the Mitzrim and light to the Yidden. Rebbe Tzadok HaKohen (Tzidkas HaTzaddik 174) explains that this is the nature of the sefirah Yesod (kedushah, tznius, shemiras einayim, etc.) When one is cautious with Yesod, he will have a lot of "light" and holiness in his life. This explains why this makah brought light to the Jewish nation. However, those who contaminate Yesod (they aren’t cautious ...
