Hi there,
I am Vinayak Singh Oberoi, or simply Vinayak. There has been a lot of sabotaging and betrayals in my family. The Publishers, weak and unjust, never properly gave recognition to the maestros of my family, starting from The State Judge to the Chemical Industrialists and inventors.
As I heard about my family and grew up learning from my mother and other relatives, I developed a strong desire to bring their work and contributions to society into the limelight. Below, you will find almost all the details of my family, starting with a small introduction about myself and then the rest.
Early Life
Vinayak Singh Oberoi, [“Vinayak Singh Oberoi” is pronounced as /vɪˈnaɪək sɪŋ əʊˈbeɪrɔɪ/] also known as Vinayak Singh, is an Indian Author and Philanthropist, born on May 7, 2006, in Kolkata, West Bengal, India. He is widely recognized for his literary contributions, including books such as “Into the Depths of Darkness” and “An Encounter with Diex.” Additionally, he has ventured into acting, participating in serials like “Karmaphaldata Shani” and “Jai Kali Kalkattawali.” Alongside his creative pursuits, Vinayak has demonstrated entrepreneurial spirit by co-developing a website named “Gypsievan” with his mother which shut down on May 11 after being active for 4 years. He has also engaged in philanthropic initiatives, particularly focusing on issues related to addiction treatment and education. Vinayak has helped fund relief efforts in flooded regions in Africa, donated to various drug rehabilitation centers, supported girls’ education, contributed to stray dog welfare, and provided food for children through the Thaagam Foundation in 2024.
Family Heritage and Naming
Vinayak’s lineage is steeped in distinction, with his great great-grandfather being none other than the esteemed Dewan of Mayurbhanj estate in Orissa, Mohini Mohan Dhar. The genesis of his nomenclature is an intriguing tale; his mother, Dr. Uma Dhar, envisioned the names “Joshua” for his affectionate moniker and “Vinayak” as his formal appellation. This thoughtful selection pays homage to the revered Goddess Parvati, given his mother’s name being “Uma.” Dr. Uma Dhar Singh, a NET/JRF-qualified Ph.D. in Philosophy from Jadavpur University, with General Fellowships in 2003 and 2013 ICPR, holds double Masters in Philosophy and Comparative Literature, a B.Ed. from Jadavpur Vidyapith, and is presently a post-doctoral fellow at Jadavpur University’s Department of Philosophy

Triumph Over Adversity
Vinayak’s entry into the world was not without challenges. His initial moments were marked by a struggle for breath, necessitating the intervention of doctors in the neonatal ICU. Fragile, underweight, and encumbered with anemia, Vinayak battled against the odds within the confines of a neonatal unit, tethered to a delicate existence by wires and a tank of life-giving oxygen. Weeks elapsed as he lay within a glass cocoon, his form still and diminutive.
However, Vinayak’s indomitable spirit prevailed, and he emerged victorious in this early skirmish, an auspicious precursor to the resilience that would come to define his character. Moreover, amidst the backdrop of his struggle for survival, Vinayak’s family was also grappling with the loss of his elder sister, Zoya Singh Oberoi, born in March 2004 but tragically passing away in the same year. Though her time on earth was brief, Zoya’s memory lingered as a poignant reminder of life’s fragility and the importance of cherishing each moment. Through adversity and loss, Vinayak’s spirit remained unbroken, a testament to his inner strength and fortitude.
Spiritual Underpinnings
From his nascent years, Vinayak was steeped in a milieu of spirituality. His mother’s account reveals a profound episode during a critical illness when she willingly relinquished all maternal possessiveness over him. In a gesture of profound surrender, she consigned Vinayak to the guardianship of the Divine Mother Kali. Thus, from childhood, he was imbued with the understanding that, “Vinayak, I am just your nanny; but your real and eternal mother is the Divine Mother.

Ceremonial Milestones
In the rich tapestry of Vinayak’s early life, significant ceremonial milestones assume prominence. The traditional ‘annaprashan’ ceremony, marking the introduction of solid food, unfolded in the sacred precincts of Yogoda Satsanga Society of India, Dakshineswar. Notably, it was not his biological parents but a Kriya Yogi from the ashram who ceremoniously administered his first grain of rice on the auspicious day of January 5th, coinciding with Paramahansa Yogananda’s birthday.

Vinayak’s journey extended to Varanasi, a hallowed city along the banks of the Ganges, where his inaugural haircut took place. Perched in his father’s lap, a poignant ritual unfolded as his mother unveiled a memento from the past — the dried umbilical cord, symbolizing his eternal connection with the Divine Mother. A subsequent haircut at Durga Mandir marked the initiation into a new phase of existence, encapsulated in photographs that would become cherished relics.
Family Dynamics and Struggles
Prominent in the tableau of Vinayak’s early memories is his relationship with his eldest aunt. A figure of unbridled affection, she stood in stark contrast to his mother’s strict demeanor. Dr. Uma Dhar, a philosopher and researcher, projected an air of erudition that defined her interactions. This familial dynamic became a crucible for Vinayak’s early perceptions, an intricate interplay of strict guidance and unbridled warmth.
The trajectory of Vinayak’s life was indelibly marked by familial struggles, notably the embezzlement of their ancestral home — a dwelling constructed by the illustrious Mohini Mohan Dhar. The repercussions of this fraudulent act, perpetrated by an unscrupulous woman, reverberated through the familial corridors, leaving an enduring imprint on Vinayak’s psyche. The trajectory of Vinayak’s life was indelibly marked by familial struggles,
Anger, Confusion, and Supernatural Intrigues
As the chapters of his childhood unfolded, Vinayak found himself wrestling with emotions of anger, stemming from financial crises and perceived betrayals. His grandfather, Chittajit Mohan Dhar, a luminary in chemistry, industry, and politics, had bequeathed a legacy that seemingly crumbled under the weight of adversities.
Intriguingly, Vinayak’s sojourn into adolescence witnessed an unexpected twist — he encountered a world of theft, lies, curses, and revenge. The supernatural, too, cast its spell, with nocturnal observations of arcane rituals involving candles and vermilion powder. The discovery of photographs, including those of his parents, fueled his fascination with the enigmatic realm.

A Demolished Kingdom- The Reason
Following the death of Chittajit Mohan Dhar in 1975, the Dhar family faced a series of unfortunate events that led to the significant loss of their wealth and property. This turmoil was largely influenced by Jyotsna Bose, a self-proclaimed spiritual practitioner, and her family.
Initial Influence
Jyotsna Bose, along with her husband Sunil Bose and son Subrata Bose, who were from an impoverished background and engaged in fishing, gained undue influence over Leena Dhar, who was struggling with asthma. Leena, influenced by a distant aunt, began seeking Jyotsna’s guidance for her health issues. Despite her initial skepticism, Leena was coerced into continuing this association due to pressures from a close blood relative, who was also a devotee.
Fraudulent Activities
By 1989, the situation took a darker turn. The Bose family manipulated Leena Dhar into various fraudulent activities. They exploited her trust and began seizing the Dhar family’s assets. The Bose family used their deceptive practices to acquire properties, including the family home on Kabir Road, and forced Leena to live in a room at a new house on Jheel Road, which was bought in Jyotsna Bose’s name.
Manipulation and Control
Leena Dhar was heavily influenced by the Bose family, who used manipulative tactics to control her. They employed deceitful methods, such as feeding her concoctions and claiming they had spiritual authority, to maintain their grip on her and the family’s assets. Leena’s mental and emotional state was compromised, making her an easy target for their schemes.
Exposure and Legal Action
Uma Dhar, Leena’s daughter, eventually uncovered the full extent of the fraud. Realizing the severe financial and personal damage inflicted by the Bose family, Uma Dhar took decisive action. She confronted the situation by appealing to local authorities, the police, and even the Chief Minister of West Bengal, Mr. Buddhadeb Bhattacharjee. Her efforts led to the arrest of Subrata Bose, although Jyotsna and Sunil Bose managed to evade capture. Sunil Bose died of vitiligo-related complications, while Jyotsna and Subrata Bose passed away under dire circumstances — Jyotsna from a heart attack while living at her daughter’s husband’s house, and Subrata from cirrhosis of the liver in a slum, near Kalighat. The Dhar Fraud Case was taken up by the High Court of Calcutta.
Aftermath
Following these events, Leena Dhar was left in a disoriented state, struggling to recall the extent of her manipulation and loss. She attempted to reclaim the stolen properties and seek justice, but the damage inflicted by the Bose family’s deceit was profound. The legal battles continued after Leena’s passing in 1996, with Uma Dhar persevering to secure justice and restore the family’s dignity.
Conclusion
The Dhar family’s descent from affluence to financial ruin was a result of systemic fraud and manipulation by the Bose family. The impact of their actions not only caused significant monetary loss but also inflicted emotional and psychological trauma on the Dhar family, marking a tragic chapter in their history.
