The Kriya Yoga LineageThe five-figure transmission chain that carries YATU's foundational chronology
Mahavatar Babaji → Lahiri Mahasaya → Sri Yukteswar → Paramahansa Yogananda → Tara Mata. Five figures, four generations, one continuous transmission. Each carries a function the others cannot. Each is publicly named, dated, and externally documented.
The framework's foundational chronology — the 24,000-year Yuga calendar restored by Sri Yukteswar in 1894 and transmitted to the West by Tara Mata in 1932-33 — reaches the modern reader through this specific chain of teachers. The page names each figure cleanly, with stable references to the publicly verifiable record.
Mahavatar Babaji
The first link in the chain — and the one most resistant to the conventional historical record. Mahavatar Babaji is named in the lineage tradition as the deathless yogi-saint of the Himalayas who, in 1861, revived the ancient Kriya Yoga technique and transmitted it to the householder yogi Lahiri Mahasaya at Ranikhet in the Drongiri mountains.
The historical particulars are recorded in Autobiography of a Yogi (Chapter 33-34) by direct disciples of Lahiri Mahasaya. The framework treats the figure as he is treated within the lineage — a transmission source whose function is to carry forward the technical practice across long historical gaps. Whether Babaji is read as a single deathless individual, a succession of bearers using the name, or a symbolic locus for the lineage's source code is left to the reader. The transmission's content does not depend on resolving the question.
What matters structurally for the YATU framework is that the Kriya Yoga technique — and the cosmological framework Sri Yukteswar would later articulate in The Holy Science — emerges into the modern record at this specific point in 1861, transmitted through a specific chain of named individuals whose subsequent biographies are all publicly documented.
Lahiri Mahasaya
Shyama Charan Lahiri, known as Lahiri Mahasaya, was born in 1828 in Ghurni, near Krishnanagar in the Bengal Presidency. He was a working householder — an accountant in the Military Engineering Department of the British Indian government — who at age thirty-three, in 1861, encountered Mahavatar Babaji at Ranikhet and received Kriya Yoga initiation.
The structural significance of Lahiri Mahasaya in the lineage is that he carried the practice from a renunciant context into a householder context. The technique that had been preserved in mountain caves became available, for the first time in centuries, to people with families and ordinary professional lives. He taught Kriya Yoga across Benares (Varanasi) for the rest of his life, transmitted the practice to thousands of disciples drawn from every caste and religion, and authored detailed Sanskrit and Bengali commentaries on twenty-six scriptural texts including the Bhagavad Gita.
Among his most consequential disciples was the young Bengali named Priya Nath Karar, who would become Sri Yukteswar Giri.
Sri Yukteswar Giri
Born Priya Nath Karar in Serampore in 1855, Sri Yukteswar took initiation from Lahiri Mahasaya in his early twenties and entered the renunciant order around 1894, taking the monastic name Yukteswar Giri. The Bengali astronomer-saint is the central figure for the YATU framework specifically: he is the author of The Holy Science (Kaivalya Darsanam), published privately in India in 1894, which restored the 24,000-year Yuga calendar to its original astronomical scale by correcting a single mathematical error that had inflated the cycle to 4.32 million years.
The error was specific and mechanical. Ancient Vedic texts described Yuga durations in divine years, where one divine year equals 360 human years. Medieval scholars working during deep Kali Yuga conditions treated these already-converted divine-year figures as if they required conversion again, multiplying by 360 a second time. The original 1,200-year Kali Yuga became 432,000 years. Sri Yukteswar's Holy Science demonstrated this mathematically and cross-referenced the restored cycle against the precession of the equinoxes — the slow rotation of Earth's axis that completes one full circle approximately every 24,000 years. The restored cycle matches the precession exactly. The inflated calendar matches no astronomical observation.
In 1894 Sri Yukteswar met Mahavatar Babaji at the Allahabad Kumbha Mela. The framework's foundational claim — that humanity is in year 328 of Ascending Dwapara Yuga, with Kali Yuga having ended in 1698 CE — descends directly from this work. He was the guru of Paramahansa Yogananda, whom he initiated in 1910 and trained for ten years before sending westward.
Paramahansa Yogananda
Born Mukunda Lal Ghosh in Gorakhpur in 1893, Yogananda was the disciple Sri Yukteswar trained for the specific function of carrying Kriya Yoga to the West. He arrived in Boston in 1920 as the Indian delegate to the International Congress of Religious Liberals and remained in the United States for almost the entirety of the next thirty-two years, founding Self-Realization Fellowship in 1920, lecturing across the continent, and establishing the institutional infrastructure for Kriya Yoga in America.
His Autobiography of a Yogi, published in 1946, became one of the most influential spiritual works of the twentieth century — translated into more than fifty languages, cited by figures ranging from Mahatma Gandhi to George Harrison to Steve Jobs (who is reported to have made it the only book he gifted to attendees of his memorial). His late-life commentaries — most notably God Talks With Arjuna: The Bhagavad Gita, completed in his final years and published posthumously — are the consolidated transmission of the lineage's interpretive tradition into modern English.
Among Yogananda's most consequential American disciples was the woman who would become Tara Mata — the editor who shaped Autobiography of a Yogi into its published form and carried Sri Yukteswar's restored chronology forward into modern English-language publication.
Tara Mata
Born Laurie V. Pratt in Salt Lake City in 1900, Tara Mata is the dedicatee of YATU and the disciple in this lineage whose work most directly grounds the book's foundational chronology. She met Yogananda in San Francisco in 1924 and became his closest editorial disciple. Her authority within the lineage is editorial and intellectual rather than monastic: she shaped the prose of Autobiography of a Yogi, served as editor-in-chief of Self-Realization Fellowship publications for decades, and wrote — under the pen name Tara Mata — the series Astrological World Cycles in East-West magazine in 1932-33.
That series is the first English-language application of Sri Yukteswar's restored Yuga chronology to world history. It carried the technical mathematics of The Holy Science out of its 1894 Indian-edition obscurity and into the modern Western intellectual record, applying the calendar to the rise and fall of empires, the historical archaeology of consciousness, and the predictive structure of the cycle ahead. Without her transmission, the framework's chronology would have remained inaccessible to readers without Sanskrit and direct lineage contact.
Tara Mata died in Los Angeles in 1971, having spent fifty-one years of her life in service to the transmission. YATU is dedicated to her. The full biographical treatment lives at /tara-mata.
