Within the broad stream of Sant Mat, the teachings of inner Light and Sound have been carried forward largely through organized satsang communities, each gathering around a living teacher or Satguru. Among the most prominent is Radha Soami Satsang Beas, based at Dera Baba Jaimal Singh in Beas, Punjab, which has become one of the largest and best-known Sant Mat–related organizations, with an emphasis on meditation, ethical living, vegetarianism, and abstention from intoxicants. Closely related in origin are Radha Soami Satsang Agra and other Agra-based branches, which trace themselves to the early Radha Soami tradition and maintain their own centers and administrative structures. These communities function not merely as institutions but as living sangats, where seekers gather for satsang, seva, and spiritual discipline under the guidance of a recognized master.

Alongside these, a number of Sant Mat lineages have developed international expressions of the path of inner Light and Sound. Science of Spirituality, which arises from the Ruhani Satsang / Sawan-Kirpal Mission stream, represents a major global manifestation of this tradition, offering meditation instruction and satsangs in many countries. Various missions associated with figures such as Sant Kirpal Singh, Sant Thakar Singh, and Sant Baljit Singh likewise focus on Surat Shabd Yoga and maintain their own communities and centers. In addition, there are Radha Soami Satsang branches such as those at Soami Bagh and Dinod, as well as other regional organizations and smaller ashrams, particularly in North India, that uphold the same essential contemplative focus.

Taken together, these organizations share a recognizable family resemblance: devotion to meditation on inner Light and Sound, a disciplined ethical life, and the centrality of a living master–disciple relationship. While they may differ in style, structure, or emphasis, they all provide a communal framework in which the solitary inner journey is supported by collective practice, regular gatherings, and opportunities for service. For a seeker drawn to Sant Mat, these communities offer not only doctrinal continuity but also a practical context in which the teachings can be explored, tested, and integrated into daily life.
