Radhasoami Prem Patra is a collection of spiritual letters associated with the Radhasoami faith, especially linked to Huzur Maharaj Rai Salig Ram, the second guru of the tradition. These letters, often understood as “letters of love,” were written by the Satguru to disciples and initiates, and they convey the essence of Radhasoami spiritual instruction in a direct, personal form. As such, the Prem Patra stands as an important body of correspondence that preserves the living voice of the master in written form, sustaining the intimate guru–disciple relationship that lies at the heart of this path.

Within these letters, the core teachings of the Radhasoami movement are articulated with particular emphasis on Surat Shabd Yoga, the inner practice of meditation on the sound current. The Prem Patra addresses devotion, ethical living, spiritual discipline, and the centrality of the living Satguru, while also offering explanations of the soul’s journey through inner spiritual regions and the broader Radhasoami cosmology. Practitioners regard these writings as authoritative guidance, turning to them for clarification of doctrine, practical instruction in meditation, and encouragement in the trials of spiritual life. In this way, Radhasoami Prem Patra serves both as doctrinal literature and as a living guide for seekers treading the Radhasoami path.
