There are many practices for which the Arya Samaj can take a fair portion if not the whole credit. They are the popularisation of the word “AUM” as a symbol of God, the use of “Namaste” as a form of greeting, the singing of “Jai Jagdish Hare” as Arti, the commencement of meetings and functions with the recital of the Gayatri Mantra and the chanting of Shanti Paath (Hymn of Peace) at the end.  The Aryan Prayer book has presented mantras to be recited at different functions in a uniform and systematic way. Priests not affiliated to the Arya Samaj also use the Aryan Prayer book in their performance of ceremonies, especially the havan, vivah and antyeshti.  Today, these practices are regarded as standard with nobody pausing to reflect on how they became so well established and entrenched.
