Archiradi is one of the 18 Rahasyas of Pillai Lokacharya that was written to expound the doctrine of the three verities (Tattva Traya). This work is organized into four cantos (prakaranas).
The first canto describes the remorseless material existence the individual souls lead in this world of bondage, followed by the onset of interest in them to know about the Divine. This interest comes through the Supreme Lord’s causeless grace, which in turn drives the souls to seek the Lord’s feet and long for performing service unto Him. As the individual soul progresses through various stages of spiritual maturity, a time comes for its separation from its gross body (sthula sarira) during death. The relieved soul subsequently traces the archiradi path via the susumna nerve of the heart, encountering various pitstops in its travel, with the journey culminating in the company of the Archiradi Purushas just outside the solar constellation.
