Satyarth Prakash (Hindi: सत्यार्थ प्रकाश, Satyārth Prakāś – The Light of Truth) is an 1875 book written originally in Hindi by Dayanand Saraswati (Swami Dayanand), a religious and social reformer and the founder of Arya Samaj. The book was subsequently revised by Swami Dayanand Saraswati in 1882 and has been translated into more than 20 languages including Sanskrit and foreign languages, including English, French, German, Swahili, Arabic and Chinese.
