Arya was a 64-page monthly review written by Sri Aurobindo (originally with the help and encouragement of Mirra's husband Paul Richard).
It ran for six and a half years and constituted the appearance in serialised form almost all of his major works except his epic poem Savitri. These included The Life Divine, The Synthesis of Yoga, Essays on The Gita, The Secret of The Veda, Hymns to the Mystic Fire, The Upanishads, The Foundations of Indian Culture, War and Self-determination, The Human Cycle, The Ideal of Human Unity, and The Future Poetry.
The first issue of the Arya appeared on Sri Aurobindo's 42nd birthday (15 August 1914), the last came out in January 1921.
