Radha Soami is a spiritual tradition or faith founded by Shiv Dayal Singh in 1861 on Basant Panchami Day in Agra, India. His parents were Nanakpanthi, followers of Guru Nanak of Sikhism, and were also followers of a spiritual guru from Hathras named Tulsi Sahib. Shiv Dayal Singh was influenced by the teachings of Tulsi Sahib, who taught Surat Shabd Yog (which is defined by Radha Soami teachers as “union of the soul with the divine, inner sound”); guru bhakti (“devotion to the master”); and high moral living, including a strict lacto-vegetarian diet. Shiv Dayal Singh frequently accompanied Tulsi Saheb, but did not take initiation from him. The movement does not promote celibacy, and most of the masters in its various lineages have been married. The teachings seem to be related to forms of 18th- and 19th-century esoteric mysticism that were circulating at the time in northern India. The founding date of the movement is considered to be 1861 when Shiv Dayal Singh began publicly to give discourses. As per some subtraditions, it derives its name from the word Radha Soami means Lord of the Soul. "Radha Soami" is used to indicate towards Shiv Dayal Singh. The followers of Shiv Dayal Singh used to consider him the Living Master and incarnation of Radhasoami Dayal .After his death, Salig Ram and his other followers started the Radha Soami movement, which later got separated into different branches/denominations, including the Radha Soami Satsang Soami Bagh Agra, Radha Soami Satsang Beas, Radha Soami Satsang Dayalbagh, Radhasoami Satsang Pipal Mandi, and Radha Swami Satsang Dinod. Nomenclature According to Mark Juergensmeyer, the term Radha Soami literally refers to Radha as the soul and Soami (swami, lord). According to Salig Ram, quotes Juergensmeyer, these terms are symbolic and mean "master of energy", derived from the Vaishnava understanding of "Radha as the power of energy of God" (Shakti). It is a referent to the consciousness in a person and the cosmic energy source, states Juergensmeyer. However, the founder Shri Shiv Dayal Singh himself never used the term. According to some other scholars, the name is derived from Shiv Dayal Singh's wife. His wife Narayani Devi was nicknamed Radha Ji by his followers.So, being the husband of Radha Ji (Narayani Devi), Shiv Dayal Singh was named Radha Soami. The writings of Shiv Dayal Singh, Sar Bachan, use the term Sat Nam, rather than Radha Soami. The gurus and the
