The Radhasoami tradition, often associated with the mystical path of the inner sound current, traces its formal origin to Shiv Dayal Singh (1818–1878), known to his followers as Soami Ji Maharaj or Soamiji Maharaj. In Agra, around 1861, he began giving public satsangs and initiating disciples, presenting a path centered on Surat Shabd Yoga—union of the soul with the divine sound current—through meditation on inner Light and Sound, ethical living, and devotion to a living Satguru. The name “Radhasoami” is understood within the tradition as referring to the supreme, formless Lord of the soul, and to the highest spiritual region. From the outset, the movement emphasized that liberation comes through inner ascent of consciousness guided by a realized Master, rather than through ritual or mere belief.

Following Soami Ji Maharaj’s passing in 1878, questions of succession led to the emergence of several lineages, all claiming continuity with his teachings. In Agra, Rai Salig Ram (Huzur Maharaj) became a central organizing figure, and the Radhasoami Satsang at Soami Bagh developed institutional structures, literature, and the construction of the Soami Bagh Samadh. Other disciples and associates also formed their own satsangs, giving rise to multiple Agra-based branches that maintained the core practice of Surat Shabd Yoga while developing distinct organizational identities. This early diversification set a pattern in which spiritual authority was expressed through parallel, rather than centralized, lines of succession.

From this matrix of lineages, several major centers gradually took shape. In Agra, Radhasoami Satsang Soami Bagh carried forward the line associated with Huzur Maharaj, while another Agra-based community, Dayalbagh, was established with a strong emphasis on community life, education, and social service, and came to be known as Radhasoami Satsang Dayalbagh. In Punjab, Jaimal Singh, connected to Soami Ji’s teachings, founded a center at Beas that evolved into Radha Soami Satsang Beas, later guided by successors such as Sawan Singh and Charan Singh. Alongside these, smaller satsangs and missions arose, each tracing its inspiration back—directly or indirectly—to the original Agra revelation of the inner Sound Current.

Despite institutional and doctrinal nuances among these branches, there remains a recognizable spiritual family resemblance. All uphold Radhasoami as the supreme, transcendent Being, and affirm that the soul’s return to this source is effected through meditation on the inner Sound and Light under the guidance of a living Master. Common disciplines include repetition of sacred names, participation in satsang, and an ethical code that stresses purity and restraint. Over time, especially through the Beas and Agra lineages, these teachings have spread beyond their North Indian roots, giving the Radhasoami tradition the character of a transregional mystical movement while preserving its foundational focus on the inner sound current as the axis of spiritual life.
