The empowering lessons of Sod Ha'adam define the essence of a Yid, and reveal the secrets to unveil every individual's greatness. This refreshingly natural approach to challenges of all kinds, opens doors wide - to a new world of unprecedented healing and building.

Sod Haadam is not only about learning - acquiring knowledge and knowhow. It’s about becoming.

How was Sod Ha’adam born?

Over the course of her work guiding students, teachers, parents, and professionals for many years, Rebbetzin Tukachinsky encountered many tough questions. Her signature warmth and deep, intuitive wisdom made her the natural address for those seeking answers. In searching for those answers, Rebbetzin Tukachinsky recognized that theTorah contains the formula for the healing and success of every Yid’s nefesh. Her revolutionary approach resulted in unprecedented change for so many. Now, through the Sod Haadam courses, Rebbetzin Tukachinsky guides thousands of women in accessing this wisdom that can transform their lives.

What is Sod Ha'adam's Mission?

Sod Haadam’s mission is to give strength and vitality to Klal Yisroel. To connect women around the world to who they are and the greatness within them. To empower them with the mission and permission to be their magnificent selves and to live the life they truly desire.

Why Sod Ha’adam?

Sod Ha’adam is unique in that its teachings are culled exclusively from Torah. Who, better than the Creator of the unique and wondrous nefesh (soul) of a Yid, can reveal to us the formula for building and healing?
Sod Ha'adam engenders real healing and growth from the foundation, thus encompassing the totality of our beings; the physical, cognitive, emotional, behavioral, and spiritual aspects.
By drawing strength from our divine core, we can access a life of joy and unlimited blessings, and form a connection with ourselves, others, and ultimately Hashem.

This secret is the birthright of every Yid. It needs to be known. It needs to be revealed.

Welcome to Sod Ha’adam.


The Founder

Rebbetzin Tzivi Tukachinsky is a
world-renowned lecturer
and teacher known for her depth, warmth,
and authenticity.


Born and raised in Bnei Brak, Rebbetzin Tukachinsky grew up in an atmosphere saturated with kedusha. At 18, she launched her chinuch career at Bais Yaakov High School of Boro Park, where she taught high school students for well over two decades.

Early on, the Rebbetzin was a confidant of many, as students and parents shared their struggles with her and received her wise counsel. Eventually, calls began to stream in from across the United States: mothers who heard of her inimitable grasp of human nature and transformative advice, asking about their children, their own challenges, shalom bayis issues, and more. Rebbetzin Tukachinsky’s revolutionary, Torah-based approach of how to work with people was producing unprecedented healing.

Today, Rebbetzin Tukachinsky is back in Eretz Yisroel, where she still guides
thousands of individuals and advises parents, educators, and therapists with her trademark perspective. She is a frequent guest lecturer at educational retreats, Y’mei Iyun, courses, and classes throughout Eretz Yisroel. She also lectures across Europe and the United States.

With this letter, I am verifying the gadlus and chashivus of Rebbetzin Tzivi Tukachinsky and her courses, which she presents to full-time mothers, well-known mechanchos, and leaders of highly respected schools and organizations.

They all attest that this course significantly enhances the beauty of their homes and enhances their lives. It is important to point out that this course is unique in that it is built b’derech HaTorah. I am warmly recommending Sod Ha’adam, from which all who join it will greatly benefit be”H. And I know that hundreds of thousands of women can testify that they already had the merit to participate in the course and thereby build their lives in a real way.

Rebbetzin Tukachinsky is well-known by many women who are deeply indebted to her for her vivid, brilliant and revealing shiurim that have empowered them to build their homes, and for having infused and uplifted their mindsets with true meaning, purpose and direction in a spirit of joy. Her rich and vast knowledge is to be marveled at; they enable all those who take her course to receive a true and proper outlook and positive thinking in each situation that they encounter throughout their lives.

I highly recommend Rebbetzin Tzivia Tukachinsky and her outstanding classes, which prove to be life-giving for Jewish women. All of her words are based upon our Torah, the words of Chazal, and Gedolei Hadoros. Here in Eretz Yisroel, her speeches have made a most significant impact; even renowned, esteemed educators and principals of the largest high schools and seminaries have attested to how they have gained substantial, genuine guidance in their Avodas Hakodesh. May she be gebentched with ongoing hatzlacha in all she does, and may she continue to infuse the pure, true hashkafos within our women, ad bias goel tzedek bimheira viymaeinu amen.
