Satyarth Prakash

Satyarth Prakash (Hindi: सत्यार्थ प्रकाश; Satyārth Prakāś; lit. 'The Light of Truth') is an 1875 book written originally in Hindi by Dayanand Saraswati, a religious and social reformer and the founder of Arya Samaj. The book was subsequently revised by 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. The major portion of the book is dedicated to laying down the reformist advocacy of Swami Dayanand with the last four chapters making a case for comparative study of different religious faiths.

Some of the topics in the Satyarth Prakash include worship of one god, explanation of the main principles of the Vedas, the relationship between religion and science and between devotion and intellect, elimination of the caste system and critical analysis of different religious beliefs and other religions in the World in the light of the Vedas, for the strengthening of society, eradication of superstitions, false notions and meaningless customs, shunning narrow-mindedness and promoting the brotherhood of man.^[2]
