Ruth Perini was born in Sydney Australia in 1947. Her love of languages began in high school where she studied Latin, French and German. She completed a Bachelor of Arts degree in French, Italian and European Philosophy in 1967 at Sydney University. In her late teens she was attracted to Buddhism because of its attitude to oneness irrespective of race, gender, time or place, and the concept of enlightenment as a means to peace.
From the age of 19, she attended yoga classes of different traditions, while working as a translator and languages teacher, and studying Japanese through Queensland University. In 1996 she began her training as a yoga teacher in the Bihar tradition. The course was very thorough, including teachings on asana, pranayama, mudra, bandha, meditation, Patanjali's Yoga Sutras and Vedanta. Later she did a distance course on The Philosophy, History and Literature of Yoga by Dr Georg Feuerstein, a wonderful teacher.
After teaching yoga classes for a few years in ashrams, retirement homes, gyms and schools, Ruth opened Epping Yoga Studio in 1999, where she held many weekly classes, and weekend programs given by senior teachers. In 2010 she began a four year study of Sanskrit at the Australian National University. Upon graduating, she was invited to join the Golden Key International Society for outstanding academic achievement, having gained High Distinctions throughout her Sanskrit studies.
In 2010 she invited Swami Satyadharma to give a program on Prana Pranayama Prana Vidya, and then started to work with her on collating teachings on Bhakti, Jnana and Raja Yoga. In 2012 they began to work together on the Yoga Upanishads, Ruth as translator of the original Sanskrit, and Swami Satyadharma as commentator. Swami Satyadharma had published her commentary on Yoga Chudamani Upanishad in 2003 through Yoga Publications Trust, when she was living in Mungher India. Swami Satyadharma and Srimukti (Ruth's spiritual name) together translated and commented on Yoga Tattwa, Yoga Darshan, Yoga Kundali, Nadabindu and Dhyanabindu Upanishads, all available on Amazon. When Swami Satyadharma died in June 2019, Ruth felt compelled to continue the work in her memory. She translated and commented on Shandilya Upanishad, which Swami Satyadharma had wanted to work on next.
Ruth has been taking classes in thangkha painting at the Vajrayana Institute in Ashfield. Swami Satyadharma encouraged her to put her painting of Green Tara on the cover of Yoga Kundali Upanishad, and Yellow Tara on the cover of their next book.
