The revolutionary truth that brought light into thousands of homes.

Transform your life and unlock your true inner splendor.

Sod Ha'adam is on a mission to help you connect with
each person in your life – yourself included.

Our Mission

At Sod Ha'adam, we believe in the unlimited power of the individual. Our present limitations make us feel small – but when we reveal our essence, we can see we are all truly giants.


How was Sod Ha’adam born?

Over the course of her work guiding students, teachers, parents, and professionals for many years, Rebbetzin Tukachinsky discerned that many people were stuck in limited mindsets, unaware of their intrinsic greatness. She helped them realize that their worldview is flipped. The illness that they saw within themselves and others turned into grace, silence and loneliness turned into connections and relationships, coldness into warmth, pain into care and sensitivity. Her experience proved that revealing the intrinsic light in every Yid is the secret to transformation.

What is Sod Ha'adam's Mission?

Sod Haadam’s mission is to give strength and vitality to Klal Yisroel. We want to connect everyone to the reality: the core of goodness and beauty that Hashem infused within us and the world, often obscured and masked by layers of darkness, confusion, galus.

What is Sod Ha’adam’s secret?

Who, better than the Creator of the world, and the source of the unique and wondrous nefesh (soul) of a Yid, can reveal to us the formula for building and healing? Culled from Torah, His wisdom, Sod Ha’adam empowers us to build ourselves and the people around us in a real way. Rather than treating the symptoms, Sod Ha'adam engenders healing and growth from the very foundation. By drawing strength from our divine core, we can access a life of joy and unlimited blessings, and form a real 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 relationship coach 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.

The incredible feedback that I have encountered over the many years is witness to the outstanding hatzlacha, all coming from a chashuve, most ehrliche, noble personality.

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.
